do I switch between self-locking and momentary mode?\u003c\/strong\u003e\u003cbr\u003eA: Solder pad \u003cstrong\u003eA\u003c\/strong\u003e on the module. Open = momentary (output HIGH while touched). Shorted = self-locking (output toggles on each touch). No code change required.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Can TTP223 detect touch through a surface?\u003c\/strong\u003e\u003cbr\u003eA: Yes. It works through non-conductive materials up to ~3–5mm thick (glass, acrylic, plastic). Thicker materials reduce sensitivity. Increase sensitivity by adding a small capacitor to the CS pad.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Is TTP223 output compatible with 3.3V ESP32 GPIO?\u003c\/strong\u003e\u003cbr\u003eA: Yes. Power the module with 3.3V and the output will be 3.3V HIGH — directly compatible with ESP32 GPIO input without level shifting.\u003c\/p\u003e\u003chr\u003e\u003ch3\u003ePackage Contents\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e5× TTP223 Capacitive Touch Button Module\u003c\/li\u003e\u003c\/ul\u003e","brand":"Keszoox","offers":[{"title":"ic","offer_id":46991482028267,"sku":"14:10#ic","price":5.04,"currency_code":"USD","in_stock":true},{"title":"module","offer_id":46991482061035,"sku":"14:350852#module","price":5.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/ttp223-touch-button-module_7.webp?v=1761545429","url":"https:\/\/keszoox.com\/products\/ttp223-capacitive-touch-button-module-single-channel-self-locking-5pcs","provider":"Keszoox","version":"1.0","type":"link"}
