Motor Adapter for NI myRIO
The Motor Adapter for NI myRIO allows you to easily connect and control either one stepper motor, two DC motors or two servos independently through the MXP connector on your myRIO. It has been designed so that no additional circuitry is required to drive motors. The board uses the Allegro A4973, a powerful full-bridge, bidirectional PWM motor controller - just supply power and you're on your way!
Servo motors are connected via standard 3-pin headers while DC motors are connected via 6-pin or screw terminal connectors and stepper motors are connected using screw terminals. PWM signals from the standard myRIO FPGA personality are routed to the DC and servo motor inputs. Motor 0 Quadrature encoder inputs are routed to the myRIO encoder inputs and Motor 1 are routed to general-purpose digital I/O. Filtered motor voltage and current are routed back to the myRIO analog inputs to enable real-time monitoring.
