Good quality, minor learning curve
The build quality is solid. It took a little trial and error to get the detection distance right for my specific enclosure thickness, but once calibrated, it works perfectly.

Sensitive and compact
Very small footprint which is great for tight spaces. Just be careful with the wiring; the pins are a bit close together if you are using thick jumper wires.

Exceeded expectations
I was worried about interference from nearby components, but the shielding on these modules is decent. They trigger consistently through a thin plastic panel.

Great for university prototypes
Bought a pack for our senior design project. The documentation online is plentiful, making integration easy. The momentary mode works exactly as described.

Perfect for Arduino projects
These sensors work flawlessly with my Arduino Uno. The sensitivity is adjustable via the solder pads, and they respond instantly to touch. Great value for the price.

Reliable capacitive switch
I replaced mechanical buttons in a custom remote control with these. They have been working for months without any false triggers. Highly recommended for low-power applications.
Q: What is the difference between TTP223 and TTP226?
A: The main difference lies in the output mode options. TTP223 typically offers direct momentary or toggle modes via solder pads, while TTP226 may have different default configurations or pinouts. Please check the specific datasheet for the variant you received.
Q: Can this module detect touch through glass?
A: Yes, it can detect touch through non-conductive materials like glass or plastic, provided the thickness is within the detection range (typically up to 5mm).
Q: How do I change the sensitivity?
A: Sensitivity and output mode are adjusted by soldering or desoldering specific test points (pads) on the back of the module. Refer to the pinout diagram included in the product manual for detailed instructions.
Q: Is it compatible with 3.3V logic systems like ESP32?
A: Absolutely. The operating voltage range is 2.0V to 5.5V, and the output is CMOS level, making it fully compatible with 3.3V systems like the ESP32 and ESP8266.
Q: Does this come with header pins soldered?
A: No, these modules usually ship without header pins soldered to allow for flexible mounting options. You will need to solder your own headers or wires.
