Description:

The MKR Motor Carrier is an MKR add-on board designed to control servo, DC, and stepper motors. The Carrier can also be used to connect other actuators and sensors via a series of 3-pin male headers.

SPECIFICATIONS :

• -Compatible with all the boards in the MKR family
• -Four servo motor outputs
• -Four DC motor outputs (two high performance + two standard performance)
• -Sensing of current feedback for the high-performance motors
• -Two inputs for encoder sensors
• -Four inputs for analog sensors (3-pin compatible)
• -Possibility to read the status of the batteries
• -ON-OFF switch with Power ON LED
• -LiPo battery connector (2S or 3S compatible) and power terminal block for alternative power source
• -LEDs to visually indicate the direction of the rotation of the DC motors
• -On-board processor for automated control of some of the outputs
• -I2C connector as a 4-pin male header:
