I really like your reviews. They are just enough to keep the mind open to others boards. but, make me feel like have enough to dig a little deeper if my project requires more. Thank you for taking the time to make it simple and easy to watch without me scrubbing or trying to get to meat of the boards. 100% im in.
I just wish that they made it with enough GPIOs to make a 104 keyboard. I'm trying to decide whether to use one of these and a I2C multiplexer or just replace the multiplexers with more of these boards as they cost about the same. Adafruit does give one of these away with ever order over a certain USD$ value before taxes & shipping. Check their website for the minimum order value as I think they change it every once in a while.
As a specialist board for mechanical keyboards this is a little disappointing. First some of the IO from the RP2040 chip has gone AWOL and for a keyboard you really want all the GPIO you can get, with maybe even a decoder chip too to maximize the number of column driver lines. Second, a single pin with a 5v level shifter would have been nice for driving a long chain of neopixels (i.e. one behind each key). You can get away with 3v3 for a small number of neopixels, but it is out of spec and it gets unreliable with a long chain, plus it means powering them from the limited current available from the 3v3 regulator rather than the raw USB 5V. Finally, for a keyboard the area of the board is not critical, but the height is since it will probably add to the height of the keys from the desk which should be minimized for ergonomics.
My dear friend, you are great but watching a video is a pain in the ass. Wrong lighting, bad camera, etc. Please get a proper camera and play a little bit with light.

Thank you very much! I have more reviews in the works :)
Adafruit included this board free in my last purchase. I don't have an interest in mechanical keyboards but I can use it like another Pico, I think.
Attempting the same.
Great video. I would love to see you design and make a custom keyboard.
Nice video clip to watch, keep it up, thank you :)

If I connect 1n 80 switch matrix to this, can it read all 80 simultaneously closed?
Why does each through hole connector have "horns"?
Those are castellations which allow you to directly solder the board to a PCB.
@@LearnEmbeddedSystems Ah, thank you - makes sense.
Please can you do a video how to setup FreeRTOS and RP2040 with open source toolchain like Gnu GCC compiler?
I'll add it to the list! Thanks for the suggestion

Thank you for your input - never been much of a custom mechanical keyboard person (not yet anyway) so it's helpful to have your input!
Obviously..make a custom keyboard Plz🙏🙏
