The RP2040-Zero is a tiny RP2040 based controller with USB-C and 20(+9) GPIO pins.
KBD.news Published December 11, 2021
I wasn't aware of this controller until m.ki aka @0002ozlet mentioned it in a
tweet about the cool836, a (closed source?) family of 30% keyboards with Alice like layouts.
Features of the RP2040-Zero:
20 easily accessible pins
9 additional pins via solder points
You can buy the RP2040-Zero on the original
Waveshare website, and also on Aliexpress.
It's still difficult to evaluate because I only used it for one of my keyboards, but it may be good because it is easier to handle than a Raspberry Pi Pico or Pro Micro thanks to its small size – m.ki.
