Digit MXP Display

The REV Robotics Digit is multi-use MXP board for interface with the roboRIO. It has four 12 segment displays, which can be used to show any letters or numbers. It also features an analog potentiometer and two momentary buttons. Teams can use the digit to display their battery voltage, select autonomous modes, tune PID variables, or display real time messages. The Digit communicates with the roboRIO using the I2C interface.

The inspiration for this product came from FRC Hall of Fame Team 1538 / The Holy Cows and their 2015 custom MXP board.
