A set of magnetic encoders for the Romi Chassis chassis. With their help, we can measure the distance traveled by our mobile robot or control the engine speed. Pololu 3542

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.

The very small step-down 6 V, 2.5 A synchronous inverter can be supplied with voltage up to 36 V, dimensions: 17.8 mm x 17.8 mm. Pololu 2859

This synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V with an available output current of around 9 A.

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.8″, but it allows a typical continuous output current of up to 5 A. Typical efficiencies of 85% to 95% make this regulator well suited for high-power applications like powering motors or servos.
