Good value

Works well but requires some tuning on the sensitivity capacitor pad for thick overlays.

Perfect for Arduino Projects

Worked straight out of the box. Very sensitive and easy to wire into my custom control panel.

5 FAQ

Q: Can I chain multiple modules?

A: Yes, each channel operates independently, so you can use multiple modules for more inputs.

Q: How do I switch to latching mode?

A: There is a solder pad on the back of the module to select between momentary and latching modes.

Q: Does it come with headers?

A: Yes, standard 2.54mm header pins are included and usually pre-soldered.

Q: Can I use this with 3.3V logic?

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

Q: What is the max touch distance?

A: It is designed for direct contact or through thin non-metallic materials like glass or plastic.
