Bit-Tree Creativity - 1-Channel Capacitive Touch Module (Non-latching / Latching / High-low Output Mode)

1-Channel Capacitive Touch Module (Non-latching / Latching / High-low Output Mode)

TTP223 is a single-channel capacitive touch-sensing IC. It requires minimal peripheral components at a low material cost. Widely deployed to replace mechanical pushbuttons for touch on-off control, dimming brightness, gear switching and other functional scenarios.

Configurable Non-latching / Latching / High-low Output Modes

Interface: PH2.0-3P

Compatible with LEGO bricks; prefabricated screw mounting holes simplify installation

BIT-TREE CREATIVITY

STEAM skills like programming will be a core competency for the next generation, and the time to cultivate this ability is now.
