The SX8634 is an i2c capacitive touch sensor with slider support, flexible GPIO pins, and non-volatile configuration storage.

As with most such sensors, circuit board layout is a special consideration. So I wanted to do it once, do it well, and be done with it for many hand-held projects to come.

This board was designed to use the default configuration of the SX8634, but there is a demo program in the repo for writing the NVM.

All boards are tested before shipping, and have right-angle headers attached unless requested otherwise. I will support requests for custom configurations specified at order-time. Email for details.

There is detailed write-up at the documentation link.

UPDATE 2021.05.05

Semtech has discontinued this part. Which is a crying shame, because I can't find something comparable with NVM. The current stock reflects the last of my units, and there will never be more. Driver support will continue.
