Programmable Digital Potentiometer

A USB Potentiometer has the capability of sending a command to the board to control the resistance output of a specific potentiometer.  Each potentiometer has 3 Connections: A, Wiper, and B.  When a low value is sent to the controller, the wiper moves closer to A, decreasing the resistance between A and the wiper (increasing the resistance between the wiper and B).  When a high value is sent to the controller, the wiper moves closer to B, decreasing the resistance between the wiper and B (increasing the resistance between the wiper and A).  It is possible to set the wipers on all outputs individually or simultaneously. 

2020 Release Date

A new line of upgraded line of USB Potentiometers will be introducted in April of 2020!
