ESP32 Forum

I am currently designing a light switch (86x86mm) that has 3 touch electrodes distributed each about a third of the switch in size, but have come across the Esp32 Hardware Design Guidelines ( https://www.espressif.com/sites/defaul ... nes_en.pdf) that states in page 25 that touch electrode diameter should be in the range of 8mm to 15mm.

So is it not possible to have a touch electrode of a larger size? What problems might be encountered?

Thank you
