I am using MPR121 touch sensor IC.
According to your application note( AN3747- Pad layout application note),
Traces for capacitive sensors should never be routed under other electrodes.
My PCB is not so big, I have difficulties in layout design.
My questions are those.
1) Can I route other traces (not for electrodes) under the electrodes?
- like LED controls lines (low frequency signal)
2) also can I put components like resistors/capacitors under the electrodes?
Thank you for yout help in advance.
