About
The Motherboard is the base-model Raspberry Pi Compute Module (CM1/CM3) carrier board for nanosatellites, providing satellite stabilization via integrated sensors on CAN bus (magnetometer, angular velocity sensor, temperature, voltage, current monitors), an EM torquer driver, and a low-power board-managing MCU with B-DOT algorithm and in-flight flash capability. The variant without the ADCS controller reduces power to just 0.25 W (sensors only) and uses only the CAN2.0B data interface. Dimensions are 86.2 × 93.6 × 14 mm, mass 55 g. Flight-qualified on SiriusSat-1/2 (launched 15 August 2018).
