The semiconductor-based touch pad is the durable alternative to classic keyboards with switches. Thanks to the capacitive measurement, the pad is also suitable for dusty or rough environments. The internal calibration detects changes in the environment and automatically adjusts the sensitivity. Technical data - Chipset: TTP229 - Supply voltage: 2.4 - 5.5 V DC - standby consumption from 2 µA - serial interface - selectable sampling rate - automatic calibration - dimensions:65 x 50 mm https://elecena.pl/product/18423567/me073-developer-boards-touch-pad-16-keys-capacitive-ttp229 2021-05-11 https://elecena.pl/product/18423567/me073-developer-boards-touch-pad-16-keys-capacitive-ttp229 2021-10-01 https://elecena.pl/product/18423567/me073-developer-boards-touch-pad-16-keys-capacitive-ttp229 2022-10-22 https://elecena.pl/product/18423567/me073-developer-boards-touch-pad-16-keys-capacitive-ttp229 2023-05-15 https://elecena.pl/product/18423567/me073-developer-boards-touch-pad-16-keys-capacitive-ttp229 2024-03-11
