The TTP223 Touch Detection Sensor Module Red Color is a single-channel capacitive touch sensor measuring just 15mm x 10mm, responding within 220ms, operating from 2.5V to 5V digital output. This touch sensor module’s 15mm x 10mm footprint makes it among the smallest touch sensor boards available, fitting into extremely space-constrained wearable builds, miniature enclosures, or projects where even the compact 15mm x 11mm variant is too large.
Per the ttp223 datasheet, beyond the standard momentary touch behavior, the TTP223 chip supports an alternative toggle or latch mode configurable through a solder bridge or pad on the board — in toggle mode, one touch turns the output ON and stays ON, while the next touch turns it OFF, functioning like a latching pushbutton rather than a momentary one. This capacitive touch sensor module’s 2.5V lower operating limit allows it to run directly from a partially discharged single lithium cell without the voltage boost circuitry that sensors requiring a 3.3V minimum would need.
this ttp223 touch detection sensor’s 15mm x 10mm size leaves very little board area for the touch pad itself, making it less comfortable for fingertip contact than larger-pad touch modules when used bare on a breadboard without an external copper pad extension. This sensor is for enthusiast and makers building ultra-compact wearable touch interfaces and miniature single-button Arduino projects.
