Shifters with extra Buttons

[tandaylor]

Hi,

I'm in the process of building my first spin2k.

I'm planning to make the shifters slightly differently. More like a watch face that can be printed in the same material as the main unit, with space for velcro straps to attach to handlebars.

Then I saw this tutorial about making a bluetooth keypad with ESP32, and wondered if I could include extra buttons to activate powerups in Zwift, or to select the rear view camera.

I'm pretty new to all this, but I'm assuming the same ESP32 unit could handle this, as long as the software was modified to include the keypad library?
