The UM7 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.

A miniature lidar proximity sensor that detects objects ranging from less than 1 mm to 50 cm by generating a PWM signal proportional to distance. It operates in a 3-5.5 V range, draws 30 mA, features an ENABLE pin for sleep mode, and holes for a 2.54 mm connector and an indicator LED. Its color, transparency, and light-sensitive properties make it ideal for robotics, automation, and contactless interfaces. Pololu 5562
