-**Overview**+**Welcome to the resource center for the 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 [[http://www.allegromicro.com/en/Products/Motor-Driver-And-Interface-ICs/Brush-DC-Motor-Drivers/A4973.aspx|Allegro A4973]], a powerful full-bridge, bidirectional PWM motor controller - just supply power and you're on your way! +Here you will find all the reference materials that Digilent has created for this board, as well as links to any external content we have tracked down. If you are interested in purchasing the Motor Adapter, visit the product page on our main website: [[https://digilent.com/shop/motor-adapter-for-ni-myrio/|Motor Adapter for NI myRIO]]
  
-Slide switches are used to select which motor configuration (servo or DC / stepper) is used. 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. One quadrature encoder input can be routed between the 6-pin connectors using a DIP switch or wired directly using screw terminals. Filtered motor voltage and current are routed back to the myRIO analog inputs to enable real-time monitoring.+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. 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. Two quadrature encoder inputs are accessible through the motor connector or through terminal blocks. 
  
-Key Features:

-  * Can be configured to work with 2 DC motors, 1 stepper motor, or 2 RC servos 
-  * Current/voltage sensing and control with high/low gain control and over-current protection 
-  * 6V-16V input voltage using screw-terminal supply connections 
-  * 34-pin female breakout allowing direct user access to signal pins 
-  * Onboard quadature encoder interface to myRIO encoder inputs 
-  * User switches for selecting servo or motor connections 
-  * Power LED indicator
