Product Description

It’s a shiny KB2040! An Arduino Pro Micro-shaped board for Keebs with RP2040. We mixed together what we liked most about the SparkFun Pro Micro RP2040 (Qwiic / STEMMA QT I2C port on the end, so good!) and Elite-C (castellated pads & pins for D+ and D-) and our existing RP2040 boards (boot button can be used for user, 8MB QSPI flash, onboard NeoPixel, jumper for skipping the diode/fuse for high power RGB LEDs or USB hosting). We even got it to all fit on a 2-layer PCB with 7/7 routing – just needed to make the smallest caps and resistors 0402.

With 20 GPIO available (18 on castellated pins, 2 on STEMMA QT port) you can easily make up to 100-keys matrices, or common 65% 5x15 layouts. Use a plug-and-play QT cable to connect to the last two pins without having to do any desoldering/rework.

Board features:

Same size and form-factor as a Pro Micro breakout and nearly-identical pinout (this board has fewer analog pins, for example)
Measures 1.3" x 0.7" without headers soldered in
RP2040 32-bit Cortex M0+ dual core running at ~125 MHz @ 3.3V logic and power. 264 KB RAM, No EEPROM. 12 MHz crystal for perfect timing.
8 MB SPI FLASH chip for storing files and CircuitPython/MicroPython code storage.
20 x GPIO pins with following capabilities:
- 18 GPIO on castellated/pin breakout pads. 2 GPIO on QT port that can be easily accessed for 5x15 keyboard layouts.
- Four12 bit ADCs
- Two I2C, Two SPI and two UART peripherals, we label one of for the 'main' interface in standard Pro Micro locations
- 16 x PWM outputs - for servos, LEDs, etc
- The 10 digital non-ADC GPIO are consecutive for maximum PIO compatibility
RGB NeoPixel for colorful status indiction
Classic green power LED
Both Reset button and Bootloader select button for quick restarts. Bootloader button is also available as a generic GPIO input button.
STEMMA QT connector on the end is compatible with the SparkFun Qwiic I2C connector, and can be used to plug and play I2C devices, or just as 2 extra GPIO pins.
3.3V regulator with 500mA peak current output
RAW output, for powering NeoPixels or other 5V devices. Jumper on bottom lets you skip over the 500mA fuse, for up to 2A from USB ports.
USB Type C connector lets you access built-in ROM USB bootloader and serial port debugging
Extra D- and D+ breakouts for alternative USB connection options.
Product Dimensions: 35.0mm x 17.8mm x 4.9mm
Product Weight: 2.8g

Please note: Adafruit has made official design changes to this board. We currently have stocks of pink PCB boards which may be replaced with black PCB boards in the future. The actual color will depend on the delivery by Adafruit.

Revision History:

As of April 24, 2022 - this board now comes in goth black and may come with black or tan STEMMA QT connectors - they work the same!
As of June 10, 2022 - This board may come with a different regulator than AP2112K due to parts shortages. The regulator can provide at least 500mA.
As of February 14, 2022 - The previous version of this board was Blinka purple, now it's a beautiful Ladyada pink! It is equivalent in all other functionality.
