STM32-Powered Base & Three Expansion Boards, All Open Hardware

mini::base is an STM32F103 MCU board with many auxiliary features, including a CAN transceiver with hardware filter and ESD protection, a microSD card slot, a 24 V power supply, an atmospheric sensor, USB Type-C support, and much more. Its compact, 54 x 42.5 mm form factor is designed to host one of our various expansion boards. We are making three such boards available through this campaign:

mini::grid is based around the SIMCOM SIM868, which supports GPS L1 C/A code and quad-band GSM connectivity. Antennas can be connected via U.FL connectors, and a nano-SIM-card slot is located on the back. A pair of Binder subminiature connectors allows mini::grid to power external hardware while exchanging CAN bus and IO data.

mini::out is a simple breakout board for the mini::base. It includes two 12-pin headers for IO access, a JTAG connector and a reset button for flashing the firmware, and a spring loaded clamp that provides CAN bus connectivity and up to 24 V of power.

mini::pit is based around the ESP32-WROOM-U, which supports both WLAN 802.11 b/g/n and Bluetooth LE. It adds a second CAN bus with transceiver, filter, and ESD protection to the mini::base. A pair of Binder subminiature connectors allows mini::pit to power external hardware while exchanging CAN bus and IO data.
