Great explanation! I'm pretty familiar with electronics so the naming conventions and nomenclature was already known, but I'm new to flight controllers and quads in general. I will be building my first in the near future. This information will be extremely useful. Thank you!
honestly sir I watched hundreds of videos and tens of webpages but this was THE BEST piece of knowledge in the best understandable form I saw on the internet THANK YOU VERY VERY MUCH, love from India, keep it up.
Check your flight controller documentation before deciding on a battery. They have an upper limit. The UART nr 2 on this board has its R2 assigned to the SBUS. If you want your LEDs to show different colors they must be addressable LEDs. SDA and SCL pads can be used for other sensors as well besides a GPS, like for example a distance sensor. M1 is by default assigned to a motor if you configure it as a flying wing or airplane. It would be nice if you explained how the RSSI and current pads are used. Great video by the way.
Hi, Thanks for watching the video and taking time to add your valuable comment. I didn't go into specifics about any board really; I was mostly trying to give an overall general idea of how flight controllers work. Knowing max input voltage for the flight controller is essential so you can have right battery voltage, or power it from an external BEC. Thanks for pointing out that there are many other sensors that could be added to the SDA/SCL pads - proximity sensors, lidar, speed sensors (pitot tubes) and others for sure. RSSI means Raw Signal Strength Indicator. It is a measure of the strength of a RECIEVED radio signal at the aircraft. It is essential know this information because it shows how much range you have left before you lose radio signal to your craft. RSSI information is essential to safe flying, but the RSSI pad is not as common to use today as 4 years ago. It is used to provide RSSI feedback for radio systems that don't do telemetry natively, for example older Flysky, FrSky and others. The setup isn't very simple. However, if you fly a newer radio system (crossfire, ELRS, ghost...) the RSSI pad isn't used because all RSSI information is sent automatically with other telemetry data. Its very simple to setup. The Cur pad is used to provide current measurements from ESC's. This information allows us to manage battery use during flights. The Cur pad is also a hold over from older ESC/Flight controller systems. It is less commonly used today in quadcopters because digital bi-directional ESC protocols like Dshot can provide that information, and so no extra wiring is needed. The Dshot protocol is most commonly used with FPV quad copters, and is much less common with other RC aircraft, boats, cars etc. This means that if you are using an esc protocol (eg. PWM / Oneshot) or firmware (eg. Blheli_S ) that doesn't support bidirectional telemetry you will need to use the cur pad to get proper ESC current readings. Safe flying Eric
@@blueskyfpv Thank you for replying. Your explanation was so detailed and clear that it solved some problems for me. I am just soldering up my first drone (my own single motor design, basically an airplane with no tail or wings). Have never even flown before. I was unsure if RSSI and the current pad were necessary, but thank you for clearing that up. 5 years ago I did not even know how to wire an LED, but youtube is very useful.
great thanks for your video. i just go a flywoo with f405 pro chip, and I am confusing where should I put my elrs receiver. in manual book tell me need 5v and UART 4, but 4 only have 4.5v another story is, I go information from another video said, the elrs receiver will power on when I plug in USB to my computer. so combine the information, you mention 4.5 and 3.3v are low amp and power on... now I have more confidence to continue my semi-first drone..
I had no idea you can get these boards. Do you use rc receiver outputs for inputs to these boards? I'm using rPi's for different things, this sounds like a fun project!
Hi thanks for the comment and questions. Raspberry Pi are great little boards to work with, but they are much more general in purpose. The boards in this video are designed for one primary purpose - remote flight control. These boards are most commonly used on quadcopters and slightly different variations are used on rc airplanes (mostly it is pin layout). They have standard UART control, so it is possible to connect components to them (GPS, RC receivers, video transmitters, etc.) As you saw in the video, there are other connector types as well (I2C being one) as well as multiple voltages available for external components. The most commonly used opensource flight software for quadcopters is Betaflight. It is designed more for free flight and racing. If you are interested in more programmable flight (return to home, position hold, waypoint missions...) then INav is the firmware you'd be looking at. They are close cousins; they just focus on different flight styles. Betaflight is only designed for "XXcopters" (tri, quad, hexa, octo); however, INav is designed for both copters and fixed wing aircraft.
"These ones" is not adult grammer. "These have this chip" and not "These ones have this chip". Are they ones or boards? Or twos? or quads? Otherwise, great video with good content are those ones
I'm happy you were able to enjoy the video. I put this stuff out to help people with their drone questions, I hope it did that for you. Thank you for the grammar tips. Cheers. Eric
This video is exceptional in all respects. First learn how to spell "grammer" before you pick on others - grammar NOT grammer. Whatever you are rattling about I do not understand. This video is absolutely great in content and presentation. I truly appreciate blueskyfpv!
Exceptional in every respect. Thank you.
Thank you for taking the time to watch. I'm glad that you found it helpful.
