This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The small 1.3×0.8″ board supports a wide 6.5V to 40V voltage range and is efficient enough to deliver a continuous 13A without a heat sink. Driver includes reverse-voltage protection along with basic current sensing and current limiting functionality. Pololu 2992

The UM7-LT orientation sensor from Redshift Labs is an Attitude and Heading Reference System (AHRS) that contains a three-axis accelerometer, rate gyro, and magnetometer. It combines this data using an Extended Kalman Filter to produce attitude and heading estimates. This LT version of the UM7 does not have an enclosure.
