Okay for the price
Works but sensitivity varies with humidity. Good for indoor projects only.

Perfect for DIY
Works flawlessly with my Arduino Uno. Very easy to wire up and the sensitivity is good out of the box.

Great replacement
Used this to replace a mechanical button on a custom control panel. Looks much cleaner.

Sensitive but good
Very sensitive to touch, needed some tuning with the capacitor pad but works well once calibrated.
5 FAQ
Q: What is the maximum load current?
A: This is a signal module. Use a transistor or relay module to drive high current loads.
Q: How do I change the output mode?
A: There are solder pads on the back labeled TOG and Q. Short the appropriate pad.
Q: Is there a protective film on the pad?
A: Yes, please remove the blue protective film before use for best sensitivity.
Q: Does this work with 3.3V logic?
A: Yes, it supports 2.0V to 5.5V so it is compatible with 3.3V systems.
Q: Can I connect this to Raspberry Pi?
A: Yes, compatible with GPIO pins. Ensure common ground is connected.
