Controller Board

The Controller Board listens to commands from the master computer and controls the game devices. It is powered by a Teensy 3.6, an ARM Cortex-M4-based microcontroller development system.

I2C

There are two I2C connectors that are +5V (level-shifted), and two that are +3.3V. Connectors for: - LED Driver Board.

SPI

There are five SPI connectors at 5V (level-shifted), on the same bus. There is another SPI connector at 3.3V, on a different bus. Connectors for: - Matrix Input Board - Input Board - PWM Output Board - Solenoid Output Board
