Continuing his series of CircuitPython/KMK/RP2040 based builds, SouthPawEngineer presents a new board with the RP2040-Zero controller (introduced late last year in KBD #56).

Happy to report the RP2040 Zero as a great little controller, and cheaper than a Pro Micro while being way more capable – SouthPawEngineer.

The Ergozero is a 40% monoblock angled pseudo-split that's similar to the Ergopi but uses a different controller. The Waveshare RP2040-Zero is a Pico-like MCU board based on Raspberry Pi MCU RP2040 but much more compact. It has 20 GPIO pins, and can be found for about $4-5 USD.

This particular board is using Choc brown switches. There's a little joystick in the middle for arrow keys, a low profile rotary encoder, a speaker, underglow RGB LEDs, and the switches are hot-swappable.
