The Driver Board provides the necessary drive circuitry for the 2D MEMS Chip and Header, allowing the user to control four analog voltages between 0 and 60V that actuate the MEMS mirror. The required power supply for the driver PCB is 3.3V/5V. The 26-pin connector on its back side is designed for connecting to the Raspberry Pi but it will work with any SPI hardware. The 6-pin connector on its front side is designed to connect to the MEMS Header with a ribbon cable.
