Switch Matrix Board

The “Switch Matrix Board” includes an array of 18 pushbutton switches. The switches are for menu and radio control functions.

As of May 2026, I am still using the original PCB design from the V11 T41. This works, however, it does not have the proper pattern of plated-through holes to attach the required 3-pin connector. This can be done with careful soldering, but the attachment of the connector will not be robust, and must be used with care.

A replacement for the V11 board is in the works and will be announced here as soon as it becomes available.

Meanwhile, the original Gerber files can be used to fabricate the board. The files are located in the Gerber folder in the repository.
