The KB2040 is an RP2040 Kee Boar Driver-board specifically designed for keyboards, resembling an Arduino Pro Micro. It integrates features from SparkFun’s 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, the Kee Boar Driver supports up to 100-key matrices or 65% 5×15 layouts, making it highly versatile for custom keyboard designs. The plug-and-play QT cable simplifies connections without the need for desoldering, making it an excellent choice for enthusiasts looking to create custom keyboards using CircuitPython.
