Touch Pads PCB [Pins]


SKU: N/A Category: Tags: ,


  • Touch pads based on Tontek ICs TTP223 – 1pins, TTP224 – 4pin, TTP 226 – 8 pins, TTP229 – 16 pins
  • For 1 ,4, 8 pins, touching indication LED is on board, you can view the status directly from the LEDs when you press it, but not for 16 pins version.
  • Can replace traditional mechanical keypads, even can use with dielectric materials as pads, high sensitive human touch sensing
  • Direct TTL signal output that can be used by MCUs or arduino
  • Very low power consumption, uA level
  • Capacitive types touch
  • 2.4-5.5V wide range power supply
  • Module can set to many different mode, low power consumption mode, IIC mode, key mode, long-time mode, rapid mode, etc, please refer this to the datasheet below. Mode can be set by jumper on board.
  • ICs need about 0.8~1.0 second for calibration when started, also auto calibration when all keys are not touched, please check datasheet for more details.
  • This module can be placed underneath any isolated materials, like thick glass, plastic case and still sensing, thickness up to 8mm, quite good at 2-4mm.

Documentation: schematic, datasheet available on this page.

    these are great. I wish that there was a 5 input ( 4 directions and a center select button) also be nice if some way to add own notation and still keep nice look….
