Adafruit KB2040 RP2040 Kee Boar Driver

The KB2040 is an RP2040 Kee Boar Driver-board designed for keyboards, shaped like an Arduino Pro Micro. It combines features from SparkFuns Pro Micro RP2040 and Elite-C, including a Qwiic I2C port, castellated pads, 8MB QSPI flash, and a jumper for high-power RGB LEDs. With 20 GPIO pins, Kee Boar Driver supports up to 100-key matrices or 65% 515 layouts. The plug-and-play QT cable simplifies connections without desoldering. Its perfect for creating custom keyboards with CircuitPython.

Features:

1. Size and Form Factor: Same as a Pro Micro breakout, measuring 1.3 x 0.7 without headers.
2. Microcontroller: RP2040 32-bit Cortex M0+ dual-core running at ~125 MHz with 264 KB RAM and no EEPROM.
3. Storage: 8 MB SPI FLASH for file and CircuitPython/MicroPython code storage.
4. GPIO Pins: 20 pins total, with 18 on castellated pads and 2 on the STEMMA QT port for easy access.
5. Analog & Digital I/O: Four 12-bit ADCs., 16 x PWM outputs., Two I2C, Two SPI, and two UART peripherals., 10 digital GPIO pins for maximum PIO compatibility.
6. LED & Indicators: RGB NeoPixel for status and classic green power LED.
7. Buttons: Reset and Bootloader select buttons for easy restarts; Bootloader button also acts as a GPIO input.
8. STEMMA QT: Plug-and-play I2C connector compatible with SparkFun Qwiic devices, providing extra GPIO.\
9. Power Management: 3.3V regulator with 500mA peak current output.
10. RAW output for powering NeoPixels and other 5V devices with a jumper to bypass the 500mA fuse for up to 2A from USB.
11. USB: USB Type-C for ROM bootloader access, serial port debugging, and extra D- and D+ breakouts for alternative USB connections.
