Documentation could be better
The module works but the pinout diagram on the back was hard to read. Functionality is fine though.

Good module, minor tuning needed
Solid build quality. Had to adjust the capacitor pads for my specific case thickness but once tuned it works great.

Perfect for Arduino Projects
Works flawlessly with my Arduino Uno. Sensitivity is good out of the box and the code examples online were helpful.

Reliable touch interface
Very responsive. Using it for a robot control panel. No false triggers so far even with vibration.

Great value for money
Bought five of these for a home automation panel. All working perfectly. Shipping was fast too.
Q: Can this work with 3.3V logic levels?
A: Yes, the module supports 2.0V to 5.5V, so 3.3V logic is perfectly compatible.
Q: Can I connect this directly to a relay?
A: No, the output current is low. Please use a transistor or driver circuit to interface with a relay.
Q: What is the maximum thickness for the touch surface?
A: It works through thin non-metallic materials, typically up to 5mm depending on sensitivity tuning.
Q: Does this come with header pins soldered?
A: It typically comes with unsoldered headers included in the package unless specified otherwise.
Q: How do I switch between toggle and direct mode?
A: There are solder pads on the PCB to select the output mode. Please check the silkscreen labels.
