    Capacitive Effect on Tracks

    Hello good time
    I designed a board that has a Micro 328 , Has 3 touch channels, and works fine, but when i put nrf on board, two of the channels don't work, and it crashes.
    But when I remove the nrf from the board and reset the micro, the circuit breaks again (I opened the nrf on the board and wired it to the board, but it didn't work again)
    What do you think it could be? I was confused whether it could be a capacitive effect or something else.

    Hi,

    EMI, EMC. Bad PCB Layout.
    Use one layer as GND plane. Use decoupling capacitors. Use HF filters.

    What on earth is an “nrf”?? National Retail Federation?

    When you post a question here don’t assume everyone knows your arcane abbreviations.
