The RP2040-based key micro RP is another board in Pro Micro size #PiDay @Raspberry_Pi
key micro RP offered by abitkeys is a Pro Micro-sized development board, similar to the Adafruit KB2040, is another option for building keyboards with the RP2040 chip, CircuitPython and KMK (waiting for CircuitPython support).
USB-C, 4MB flash, Pro Micro compatible pinout, but this one comes with some interesting differences.
E.g. “side-push” Reset/Boot switches pointing to a direction where, depending on your layout, you can use them even when the board is soldered reversed.
In addition, extra Reset/Boot switches can be soldered on the back side. No LEDs and the PCB is a completely black print-free board.
Regardless of its availability, the board is fairly expensive, about $17, compared to a $4-5 Pico or $9 KB2040.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
