Vendor Documentation

Arduino USB PIDs

The Holoseat Test Stand uses Arduino boards to interface with the motor and sensor. The USB VID and PID are required by the Holoseat serial library used to connect to these boards to ensure it only queries the appropriate devices for the presence of the test stand firmware. The following list covers the VIDs and PIDs for all boards Model B has access to for purposes of building test stands.

Holoseat Test Stand

The Holoseat Test Stand is a development and manufacturing resource for Model B's Holoseat. Developers can use it to simulate user activities in predictable and repeatable testing. And the manufacturing team can use the test stand to verify the key sub-systems (sensor, tone ring, and controller) are assembled correctly and work according to their specifications.

Key resources for the test stand are:
