It requires only one ADC pin on your microcontroller to read all 5 buttons, significantly saving I\/O resources. Compared to matrix keypads, it simplifies wiring, offers good noise immunity, and supports software debouncing. The board features a PH2.0 3‑pin connector, operates at 3~5V, and has M4 mounting holes compatible with LEGO bricks. Ideal for I\/O‑constrained projects.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"font-size:22px;font-family:arial, helvetica, sans-serif\"\u003eSpecifications\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003e●Supply Voltage: 3~5V\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003e●Number of Buttons: 5\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003e●Output: Single analog voltage (read via ADC)\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003e●Connector: PH2.0 3‑pin\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003e●Module Size: 38.4×22.4mm\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003e●Mounting: M4 screws (compatible with LEGO holes)\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cspan style=\"font-size:22px;font-family:arial, helvetica, sans-serif\"\u003e\u003cstrong\u003ePackage\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003eADC Button Module × 1\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003e3Pin PH2.0 to Dupont Cable × 1\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003eLego Compatible Brick Base × 1\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sf85a9f0ff4d247aea98d7e82e615dbc2Q.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S458bbcf09383437fbfbb2f408dc7d5dbL.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sb676fb107fef4e0fb0dcae5058dc4146p.jpg\" slate-data-type=\"image\"\u003e\u003c\/p\u003e","brand":"Yoeruyo","offers":[{"title":"ADC Button Module \/ China Mainland","offer_id":55077781668139,"sku":"14:1202#ADC Button Module;200007763:201336100","price":11.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/5744\/8747\/files\/Sa486068f00794ba0aa24adec3284ee3eQ.webp?v=1787717114","url":"https:\/\/yoeruyo.com\/products\/adc-button-module-5-keys-single-channel-voltage-divider-3-5v-saves-i-o-pins-for-arduino-esp32-micro-bit","provider":"Yoeruyo","version":"1.0","type":"link"}
