Briefly, it’s a Raspberry Pi v1, Model B, Rev2 breakout with an STM32F030 microcontroller connected to the Pi UART, with all GPIOs for both broken out. There are also connectors for an NRF24L01+ module, a 12V boost module, and 315/433 Mhz wireless transmitters.
One board will serve as my Garage Door Controller, while the others will be used for general Pi hacking.
