On Raspberry Pi, enable I2S audio in config.txt. Check power and speaker connections.\u003cbr\u003e❓ Distortion or low volume?\u003cbr\u003eCheck GAIN pin setting. Default gain is 12dB (GAIN tied to GND). Adjust for higher volume if needed.\u003cbr\u003e❓ Can I use this with Arduino?\u003cbr\u003eYes, but only on boards with I2S output (Arduino Due, Zero, MKR series). Uno\/Nano do not support I2S – consider using an I2S audio module.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;font-weight:bold;text-align:left;color:rgb(67, 70, 73)\" class=\"word-break white-space mt-10\" align=\"left\"\u003eSpecifications\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg style=\"width:100%;height:auto\" width=\"100%\" height=\"auto\" src=\"https:\/\/ae01.alicdn.com\/kf\/S970388316f7a41e8bd9401ac2cb563abA.jpg\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\n\u003cp style=\"font-size:16px;font-weight:bold;text-align:left;color:rgb(67, 70, 73)\" class=\"word-break white-space mt-10\" align=\"left\"\u003ePackage Includes\u003c\/p\u003e\n\u003cp style=\"font-size:13px;font-weight:normal;text-align:left;color:rgb(67, 70, 73)\" class=\"word-break white-space mt-10\" align=\"left\"\u003eSingle Module (Unsoldered): 1 × MAX98357A Audio Amplifier Module (Headers NOT Soldered)\u003cbr\u003e\u003cbr\u003eSingle Module (Soldered): 1 × MAX98357A Audio Amplifier Module (Headers SOLDERED)\u003cbr\u003e\u003cbr\u003eWire Kit: 1 × Module (as selected) + 1 × Female‑to‑Female Jumper Wire Set (20cm, 4 pcs) + 2 × Speaker Wires\u003cbr\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Electroeshop","offers":[{"title":"Big chip NO solder","offer_id":52437167603748,"sku":"14:350850#Big chip NO solder","price":5.15,"currency_code":"USD","in_stock":true},{"title":"Big chip soldered","offer_id":52437167636516,"sku":"14:366#Big chip soldered","price":5.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/9839\/9780\/files\/S2cbaf6c505894955abb58de2b106e29aF.webp?v=1790661554","url":"https:\/\/electroeshop.com\/products\/max98357a-i2s-3w-class-d-audio-amplifier-module-dac-decoder-filterless-plug-and-play-for-esp32-esp8266-raspberry-pi-arduino","provider":"Electroeshop","version":"1.0","type":"link"}
