I'm absolutely in love with the RPi Pico. I bought 25 or 30 of them for different projects. And thinking about how you upload the firmwares into it, I thought that it was a wrong way of doing that; but now I realize that this is the best, avoiding the users to buy an expensive hardware programmer. I'm totally expecting the new generation of RPI Pico (version 2, maybe?) with more SRAM, 4 cores and more I/O processors (and more pins?? It could be very competitive in FPGA-related applications)... Thanks RPi Foundation!!!!!!
Could the pin numbers also be on the front of the board? They're kind of hard to see when you've soldered the board or have stuck it into a breadboard.
My goto strategy is to solder the headers on up-side-down, then plug it into a bread board with the bottom facing up. you may have to also use an external button for resets, but this is generally not hard as most micro controller breakouts have a dedicated reset pin
This is going to save so much money for makers who have been using pi zeros (a computer with half a gig of RAM!) for tiny projects that are only using a couple of GPIO pins. I like it!

No OS, the bootrom runs a bootloader which runs bare metal ARM binaries like micropython. No indirection (unlike ESP32's FreeRTOS layer) needed. No, python is not interpreted unless you're using the REPL over the serial port to type out individual lines of code and run them. Otherwise, the micropython bytecode compiler is invoked; and the runtime executes the bytecode after caching it. Code is still stored in an uncompiled plain text form before bytecode conversion, or can be converted into a .mpy bytecode for deployment if you don't wish to distribute the plaintext source. And yes, USB Mass Storage's FAT Filesystem is simulated by the 2nd stage bootloader held in the 2MB flash chip; completely synthetic and never needs to be fscked/chkdsk'd, and will always show up marked as "clean", ready for the host machine's OS to mount.
At that point your just better off getting an esp232. The reason this thing is exciting is becuase for its bang for my buck. I know that adding those featueres will increase picos price and then its not as attractive:(
i have a speedo meter works on encoder. encoder purse rate 0- 500 pulses per second on both channel A & B .my meter has 5% errror i wanted to feed this to micro controller and make 5% more pulses out put on both channel to compensate the error. (for examble if frequency 100 hz i need 105 hz output) could you please guide me
Would it makes sense to use a RP-Pico to make a startup/safe shutdown switch for a mobile raspberry pi 4 project? The pico uses such little power that you could have the pico monitor a switch for powering on the Pi4 and for monitoring the battery level? So the pico would always be running and could cut the power or start the power to the Pi4 and possibly also monitor battery level of the system? Does that make sense?
264KB of RAM is such an odd size... You can address a maximum 256KB of RAM with 18 address bits, so for the addition of only 8KB more RAM, you have to add a 19th bit to your CPU's addressing system (and the bus, and all the rest of the subsystems). Unless you plan to release one that has 512KB of RAM at some point, in which case it would make sense... Anyway -- neat device you have here! And for only $4?! Makes me want to buy one just so I can figure out things to do with it. :-)
There are several different microcontrollers, such as the Arduino. That's a whole family of different boards, with variations in inputs and outputs. So is the Adafruit feather system of boards and add-ons. Not really duplicates, but people might not want the hassle of crossing over to a different family. Once thing the Pico has which is new in the Pi family is the ADC inputs. Bit of a superficial read so far, but it looks as if a Pico could convert an old-style analogue joystick to USB.
@@raspberrypi I now have read the documentation on the blog post. It's certainly very extensive. Obviously, there's a lot of work already done on C programming side. Why not even a mention? It feels like you are promoting python at the expense of everything else. Maybe this dates me, but I always think embedded computer programming involves cycles and bytes counting, and that means Assembly language, or C. None of these higher level languages such as C++ or Python. I think this board is excellent for learning C and Assembly, and I hope that there would be resources dedicated toward that endeavor beyond a simple introduction. Otherwise, it'd feel like a wasted opportunity. But then again, maybe it's just me. When I learned FPGA programming, I wanted to know how to program specific individual gates, but found no information on the subject. Obviously, nobody else wants to learn that, or even think that's actually worthwhile.
@@simpletongeek There's a place for assembly and cycle counting in the Raspberry Pi microcontroller (RP2040); primarily in the PIO state machines, which can run at configurable rates. They're not CPUs, but allow you to do real time logic independently, like video or sound output. Combined with the multiple memory banks and bus crossbar, you can design your own choice of dedicated hardware. It's quite neat IMHO. Most FPGAs don't have a lot of individual gates, by the way, but use LUTs and muxes. Actel (now Microsemi) sea of gates models are the exception. Manufacturers seem opposed to the idea of people knowing everything about their FPGAs, but projects like Icestorm support a few models. Xilinx Lava was an interesting design language with the ability to plan not just logic but its placement.
The official Raspberry Pi board will run off anything from 1.8-5.5V but doesn't have power management, so you can use LiPo, but you'll need to charge with a different device. But Adafruit have announced an RP2040 version of their Featherboard, and that has battery management and charging onboard. Full details on the RPi Foundation's announcement: www.raspberrypi.org/blog/raspberry-pi-silicon-pico-now-on-sale/
Since Pi Pico does not have wifi or ethernet, can it communicate with Raspberry Pi 4? over UART may be? Its like Pi 4 being a central hub & a dozen Picos gathering data & communicating Pi 4.
Hahaaa! I ordered 10 from sparkfun! this morning. couldn't be more happier! Ingenious!! Now all we need is a RPi4 in a zero form factor. Also , I'm eagerly looking forward to the sale of the silicon chip alone. Can't wait to start using C language with this. so many capabilities! i can't wait!
I'm new to raspberry pi. Does the board come with preload bootloader? I don't want go through the process of burning bootloader to the board. Can I write the code in Visual Code and upload to the board?
Board comes with a 2nd stage bootloader on the 2MB SPI NOR flash for consuming .UF2 files delivered over USB Mass Storage. You buy bare RP2040 chips and you either fork the foundation's bootloader, or write your own. Write your code in Visual Code, click compile, and it should spit out a .UF2 file instead of a .hex, .bin, or .raw. No need to use a serial programming application like esptool.py or ponyprog, ETC. Just drag the .uf2 file over. Soon as the file handle is closed, it'll write the image to the SPI NOR flash and restart itself immediately into your code. Can also script delivery of a .UF2 whenever an appropriate device appears (as you must hold bootsel to enter programming mode first.)
If you code it that way then yes, the same way that all single core chips can switch back and forth between which program, or part of the same program, that they are running.
Is there a relatively straightforward way to add a second USB port to it, perhaps even just dedicating one of the cores to running the second port entirely in software? I'm looking to make a little macroing keyboard that converts keypresses or controller button presses for custom shortcut keys and was going to use a ZeroW and connect it to the PC with Bluetooth, but this looks like it would be more efficient if I ran it as a pass-through USB dongle, powering itself and the keyboard or control pad off the USB bus power.
I doubt it, but I think you can just skip the Pi Zero enterly and use just a PICO if your making a macro keyboard. Unless you mean you want it to be a macro keyboard for a pi zero which will also have another usb device. In that case, you could get a MCP23017, which lets you give anything with an I2C port 16 extra GPIOs, which should be plenty for a macro keyboard. That's 64 buttons if you use active polling. Or a small usb hub like maybe this one designed specifically for the RPi0 www.adafruit.com/product/3298
although strictly speaking you could just wire some buttons to your pi zero's GPIOs and write a script to check if the buttons are pressed then emit a key combo or whatever if so
Why do I need to drag and drop the UF2 file onto the controller if I got it from an html page I also accessed from the same Controller? Doesnt that mean it is already there?
Question, i plan on building an "autonomous" rc car, i basically want to remove the rc part, and make it that it drive itself to the setted designation, with the vehicle correcting its path via sensor input Microcontroller or small pc like pi 3/4?
IMO, both. Use the microcontroller to make a permanent interface to the servos. Use the SBC for vision/sensors. Connect the two via USB. Later, when you outgrow your SBC, you can get a faster one without having to rewrite all of your motion-control code. Use something like the pico as a GPIO to USB bridge. This is also quite handy when dealing with DC motors and the like, which are often noisy and cause power brownouts; the MCU can tolerate such things much better than an SBC's boot time of up-to-tens-of-seconds, and fscks of up-to-tens-of-hours based on storage size. It also adds a margin of safety; if your DC motor gets a drop of water inside and fries something, it'll be the cheap replacable pico, not the $15-to-$350 SBC. USB Webcam & a Pi4's a good starting choice, with eyes on a Jetson Nano B01 [1] to replace it once you get more confident with machine vision libraries. Look into ROS.org [2], the robot operating system, and it's companion ROS nodes for microcontroller motor drivers.

@@supahx1421 More libraries available. More community support. Less details to juggle so easier to maintain. Less hardware specific code so can run in more places, including browsers, watches, TV's, cars and iPhones without permission from Apple.
Well considering that arduino nano cost half of pico's price and cheapest Attiny(can be programmed using arudino IDE and arduino as ISP ) cost quarter of pico's price, i bet that arduino will be living for a while, i mean yes pico have great parameters, bu there are quite a bit of applications where this is overkill and arduino or even Attiny would do the job for smaller price. But of course i wish long life for both brands.
Honestly, I don't like it. Being pretty much advanced with SBCs and usually coding microcontrollers in Assembly rather than, uh, Python, I'd deem this board cool if it was half of its size. It seems half of the PCB is empty anyway, and the only point of making it so big is to accommodate all that GPIO nobody would never use to full extent. How about an option to snap off a useless half of the board?
Tl;DR: THIS IS NOT A COMPUTER. It's a Pi Zero that consumes 20x less power and comes with storage and a temp sensor. It can run on double A batteries for a year with good batteries and a little optimization, while supporting cameras and RF transmission. #RIPArduino
@@yeet1337 kinda what I meant... It's made by the foundation, has the same-ish usb port, similar GPIO and feature rich silicon. On the flip side, this microcontroller is powerful enough to pass as a computer in the 80s I posted that because I originally didn't see the point of this when a Zero costs on extra dollar and has 40 times more RAM. It's about milliwatts more than anything.
"Pico-" is a prefix that already existed, it's at the very small end of the metric system. While being silly and calling it like that is possible, nobody would do that since pico is a pre-existing word.
I wish it had type-c cable variant, other than that perfect
or the usb mini. the micro its very problematic. it breaks easily or become loose. the mini its rough
It seems Adafruit is making one that is smaller and has type c
Adafruit Feather RP 2040 has usb-c 🙂
Usbc will not be profitable at 4 dollars. Also pico only supports usb1.1 which means extra pins increase cost and manufacture failure rates

@Richard Harris, yes, it is fast enough for video for VGA standard resolution.
No WiFi
I liked this explanation. It's quite clear and useful.
So in theory, could I use this as a way to add more GPIO pins to my current raspberry pi?
yes, as long as you dont need realtime output from those pins into your PC (and even that should be achievable somehow...)
Providing you have a program talking to the Pico to tell it what GPIO pin action it should take, yes.
Yes if you devise a way to communicate with the Pico from the Pi. But it is much better to use IO expander chips that are made for this purpose.
Yup! you'd be using this as a multiplexer!
It's supposed to be standalone.
This looks so cool, I can't wait to get one of these

It also adds a margin of safety; if your DC motor gets a drop of water inside and fries something, it'll be the cheap replacable pico, not the $15-to-$350 SBC. USB Webcam & a Pi4's a good starting choice, with eyes on a Jetson Nano B01 [1] to replace it once you get more confident with machine vision libraries. Look into ROS.org [2], the robot operating system, and it's companion ROS nodes for microcontroller motor drivers.

Any updates on the 'autonomous' rc car???
Can it have TypeScript?
Nah only C and python
I guess you can transpile the Typescript to Python. Other than that, not really
This is what I've waiting for...
can i code in that... because i am a beginner...
yes, using micropython
USB-C? Please?
Teensy 4.0
Is it the teensy $4?
You had me until Micropython... Get Deno, Dart or Typescript to support this and we'll have a revolution
Why would you ever use a high level “programming language”?
@@supahx1421 More libraries available. More community support. Less details to juggle so easier to maintain. Less hardware specific code so can run in more places, including browsers, watches, TV's, cars and iPhones without permission from Apple.
Awesome....
why micro-usb and not usb-c ?
usb C doesn't support USB 1.0 protocol, which is where the PICO tops out at. microcontrollers can rarely pull of USB 2.0, much less 3.0 and beyond
💘 😘 😘 😘 😘 😘 😘 😘 😘... Seriously waiting this to happen... Lol rip arduino 😜... But I also love arduino 💕
Well considering that arduino nano cost half of pico's price and cheapest Attiny(can be programmed using arudino IDE and arduino as ISP ) cost quarter of pico's price, i bet that arduino will be living for a while, i mean yes pico have great parameters, bu there are quite a bit of applications where this is overkill and arduino or even Attiny would do the job for smaller price.
But of course i wish long life for both brands.
Brian Lough?
$3 microcontroller has more features than a $25 arduino uno
Honestly, I don't like it. Being pretty much advanced with SBCs and usually coding microcontrollers in Assembly rather than, uh, Python, I'd deem this board cool if it was half of its size. It seems half of the PCB is empty anyway, and the only point of making it so big is to accommodate all that GPIO nobody would never use to full extent. How about an option to snap off a useless half of the board?
can the micropython be programmed to run a car engine EFI system?
Probably. Do you want to do that? Probably not. :-D
Tl;DR: THIS IS NOT A COMPUTER. It's a Pi Zero that consumes 20x less power and comes with storage and a temp sensor. It can run on double A batteries for a year with good batteries and a little optimization, while supporting cameras and RF transmission. #RIPArduino
It's not a Pi Zero in any way except maybe the form factor lol
It's not a Pi Zero, no way no how. It doesn't have floating point arithmetic, for a start.
But yes, #RIPArduino
@@yeet1337 kinda what I meant... It's made by the foundation, has the same-ish usb port, similar GPIO and feature rich silicon. On the flip side, this microcontroller is powerful enough to pass as a computer in the 80s
I posted that because I originally didn't see the point of this when a Zero costs on extra dollar and has 40 times more RAM. It's about milliwatts more than anything.
Missed a trick in not calling it the Raspberry Pi-co (pie-co), and not 'peeco'. ;)
"Pico-" is a prefix that already existed, it's at the very small end of the metric system. While being silly and calling it like that is possible, nobody would do that since pico is a pre-existing word.
I love screwing around with microcontrollers.

Stick WiFi on board, and the job's a good 'un
Why is this cheaper than a real raspberry pie?
