+A wild Kee Boar appears! It’s a shiny **KB2040**! An Arduino Pro Micro-shaped board for Keebs with RP2040. (#keeblife 4 evah) A lot of folks like using Adafruit parts for their Keeb builds – but with the ItsyBitsy not being pin-compatible with the Pro Micro pinout, it really wasn't very easy without some sort of adapter plate.

+Now we’re seeing lots of people use CircuitPython for keebs, which is awesome! So why not try our hands at spinning up a pro-micro-compatible RP2040 board? The RP2040 is plenty powerful, low-cost, and makes for an excellent keeb driver chip.

+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](https://www.adafruit.com/product/4209) without having to do any desoldering/rework.
+
+Board features:
+
+- [Same size and form-factor as a Pro Micro breakout](https://www.sparkfun.com/products/12640) 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.
+  - Four 12 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](https://learn.adafruit.com/introducing-adafruit-stemma-qt/what-is-stemma-qt) on the end is compatible with the [SparkFun Qwiic](https://www.sparkfun.com/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.
