Hatched ground is recommanded in Espressif’s Touch Sensor Application Note for the area arround the touch sensors. Afaik Fritzing has still no feature in this direction. I found this Feature request: Hatched ground planes what I would support and this thread How can I add hatch fill for a project? as a complex workaround. Any other hints or workarounds for a hatched ground?
Any ESP32 user here? What did you use – beside the PCB touch area and the ESP’s touch sensor pins – as additional components? Is a series resistor necessary or in what circumstances?
Btw many thanks for this tutorial, Steve / @steelgoose!
