  • RE: TIDM-1021: About single-sided mounting

    Hi Dennis, Thank you for your reply. When looking at TIDM-1021, RX traces is hidden behind the board and just above the front seems to be hatched with TX. My idea's concern is that the RX trace will be exposed on the touch surface and will falsely detect…

  • RE: TIDM-1021: About the size of the hole of the RX electrode button

    Hi U-SK, Making the LED holes larger will impact the sensitivity of the button. The less copper sensor area there is to interact with a person's finger, the more you will have to increase the sensor's sensitivity to compensate for this. One solution…
