Needs careful wiring
Works but picked up some noise initially. Shielding helped. Good for the price.

Good value
Does what it says. Had to adjust the sensitivity pad slightly but works well now.

Perfect for Arduino Projects
Works flawlessly with my Uno. Very sensitive and easy to configure for latching mode.
5 FAQ
Q: What is the maximum thickness for the touch surface?
A: Typically works through up to 5mm of non-metallic material like plastic or glass.
Q: How do I switch between latching and momentary?
A: There is a solder pad on the back. Shorting it sets latching, open sets momentary.
Q: Can this drive an LED directly?
A: Yes, but ensure the current draw does not exceed the module's output capability. Use a resistor.
Q: Is there a way to adjust sensitivity?
A: Yes, there is a sensitivity adjustment pad on the PCB for fine-tuning.
Q: Can I use this with 3.3V logic?
A: Yes, the module supports 2.0V to 5.5V operating voltage.
