Perfect, functional and recommend
Mały sensor dotykowy na układzie TTP223. Istnieje możliwość regulacji czułości układu przez zmianę wartości kondensatora w zakresie 0-50pF.
Vin,GND and data to source Vin... Force it on over 7v, than start doing crazy things :) So use it at 5v or less, less V smaller radius. On 5v radius is around 3 cm, dont put it under metal, use wood or plastic, any conductor will trigger it. I use it to turn 0.96 inch OLED on my alt/press/temp meter, saves battery and make it look like proper consumer product not electro freak gadget. Normaly open, normaly close or touch, your choice. Check where to solder to put in state you need for your product/project.
Works very well. It was really good purchase.
I really love these touch switches. With them, my PC turns on by touch now.
Everything is ok
Very good products
