Great replacement for buttons
Using these to modernize an old control panel. Looks sleek and functions well.

Okay for the price
One channel was less responsive than the others. Still usable for hobby stuff.

Good but sensitive
Works well but picks up noise if wires are too long. Keep it close to the MCU.

Works perfectly with Uno
Very easy to integrate. The touch sensitivity is spot on for my project.
5 FAQ
Q: Is there a sleep mode?
A: The chip has low power consumption but does not have a dedicated sleep pin on this module.
Q: Does it come with headers soldered?
A: No, headers are not included to allow flexible mounting options.
Q: Can this run on 3.3V logic?
A: Yes, the module supports 2.0V to 5.5V, so 3.3V is perfectly fine.
Q: Can I use this with water nearby?
A: Capacitive touch can be affected by moisture. Keep the module dry for best performance.
Q: What is the max current per output?
A: Please refer to the TTP224 datasheet, but we recommend driving a transistor for loads over 5mA.
