Motorized Lens Control Board

Motorized Lens Control Board

For ease of evaluating Theia’s motorized lenses Theia offers a motor control board. This board allows the user to control zoom, focus, P-iris, and IR cut filters (there is no control for DC auto iris lenses). For evaluation, we offer a Windows based test program to communicate over USB. You may also communicate over i2c or UART from within your own program. Details are covered in the instruction manual from the link below, as well as CAD model and drawing of the board.

Theia Motor Control Board Instructions


There are 3 options for the controller board. Choose the correct model based on your lens.


The board is intended to be used as an evaluation board in industrial and laboratory settings. Any use in a production environment will require the customer (you) to fully evaluate the functionality, lifetime, environmental, and other specifications and to apply and obtain necessary certifications.

The evaluation software is provided as is and without warranty.  Any software we published (source or compiled) that is intended to control the motor controller boards from other hardware (i.e. PC, Raspberry Pi) is given for demonstration purposes only with no usefulness or functionality expected or implied. You are free to use it as you see fit - free of charge - but by such use you are accepting full responsibility for any consequences of such use, including but not limited to any financial obligations.
