The PillBug is a BLE enabled development board powered by the nRF52840 that is designed to be a drop in replacement for the stm32f401/stm32f411 blackpill development board. This board was designed for compatibility with blackpill driven keyboards and will work as a simple replacement in most cases. The PillBug features 3.7V Li-Ion battery charger, a software controlled hardware cutoff for powering peripherals, a controllable status LED, and compatibility with blackpill's pinouts for I2C/SPI/UART.
