TTP223 RED
Rs. 6.80
The TTP223 Touch Key Module (red) is a single-channel capacitive touch sensor IC module replicating a single tactile button. 11×10.5mm sensing area, ~5mm range. Output configurable via solder jumpers: momentary or latching, active-high or active-low. Onboard LED. Auto-calibration every ~4s. Allow ~0.5s stable time after power-on before touching.
Output Modes (AB jumpers):
- AB=00: No-lock High TTL
- AB=01: Self-lock High TTL
- AB=10: No-lock Low TTL
- AB=11: Self-lock Low TTL
