OpenLIDAR PCB v0

The OpenLIDAR PCB comes standard with the Xaxxon OpenLIDAR Sensor, and it's available by itself for your custom sensor integration project.
It runs the Garmin Lidar-LITE v3 laser range sensor, drives a stepper motor, uses a photo sensor to precisely track revolutions, and interfaces with a host system via USB. Power distribution design allows both the stepper motor and sensor to run reliably on the minimal power provided by a host-system's USB jack, while separating motor noise from the range sensor i2c communication.
