DC Motor x2 MIC (ME-00047-1A)

ABOUT
The Magzor DC Motor MIC provides you with independent control of up to two brushed DC motors. This MIC is capable of driving loads from 2.7 V to 10.8 V at up to 1.5 A (@5 V). The board uses convenient JST-EH connectors for each of your motors.

Power
The board accepts 3.3 V input for the MSP430G2553 microcontroller and I2C bus. The board supports input up to 10 V for VCC to supply the motor with up to 1.5 A (@5 V) per motor/H-bridge (check specifications for your motor).

Connectors
The boards has two convenient JST-EH connectors for your motors and two standard MIC stacking headers for power and I2C communication, as well as a 3-pin right angle header for programming the microcontroller.

MSP430G2553
The MSP430 is a low-voltage mixed-signal 16-bit microcontroller. This chip serves as the brain of the DC Motor MIC, managing I2C communication and serving as the translator to the dual h-bridge driver.

BC817 NPN Transistor
This general purpose transistor is used to trigger the flag pin on the I2C line from the microcontroller.

DRV8833PWP
The DRV8833 is a dual h-bridge motor driver used to control the speed and direction of up to two dc motors.
