Okay for beginners

Functionality is fine but the pins were not pre-soldered which was a bit inconvenient.

Good sensitivity

Works well but needed some tuning on the sensitivity pad for my specific enclosure.

5 FAQ

Q: What happens if I touch the back of the PCB?

A: The sensor pad is on the front. Touching the back may cause interference but won't trigger the switch reliably.

Q: Is this compatible with 3.3V logic?

A: Yes, the operating voltage range is 2.0V to 5.5V, so 3.3V is supported.

Q: Can this detect touch through glass?

A: Yes, capacitive sensors can typically detect touch through thin glass or acrylic up to 5mm.

Q: Do I need a library for Arduino?

A: No library is strictly needed as it acts like a digital button, but libraries can help with debouncing.

Q: Can I connect multiple modules together?

A: Yes, you can connect multiple modules to different GPIO pins on your microcontroller.
