MD25 - Dual 12Volt 2.8Amp H Bridge Motor Drive

Overview

The MD25 is a robust I2C or serial, dual motor driver, designed for use with our EMG30 motors. Main

features are:

1. Reads motors encoders and provides counts for determining distance traveled and direction .

2. Drives two motors with independent or combined control.

3. Motor current is readable.

4. Only 12v is required to power the module.

5. Onboard 5v regulator can supply up to 1A peak, 300mA continuously to external circuitry

6. Steering feature, motors can be commanded to turn by sent value.

7. Variable acceleration and power regulation also included

Connections

Jumper Selection I2C mode with no jumpers installed, up to 100 khz clock. Serial mode at 9600 bps, 1 start bit, 2 stop bits, no parity Serial mode at 19200 bps, 1 start bit, 2 stop bits, no parity Serial mode at 38400 bps, 1 start bit, 2 stop bits, no parity Motor Voltage The MD25 is designed to work with a 12v battery. In practical terms, this means the 9v-14v swing of a flat/charging 12v battery is fine. Much below 9v and the under-voltage protection will prevent any drive to the motors.
