Board 1:
Custom board 1 is a 2-layer PCB that sits above custom board 2. This board holds the components for the three-axis gyroscope used in sensing the CubeSat’s rotation.
Board2:
Custom board 2 is a 2-layer PCB that sits underneath custom board 1. This board contains the components for switching power to two cameras, power switching for the two burn-wire mechanisms used to release the antennas, and switches for sensing antenna deployment. Additionally, this board also serves as a mounting point for the Z-axis permanent magnet used in attitude control.
