Lithium powered speaker with 4 ohms 3W+3W, voltage regulator Power 5V speaker with 4 ohms 5W+5W. If the current is not enough, there will be a jump or Bluetooth instability, the motherboard will always restart or the sound quality is not good \/ broken \/ distortion and other bad phenomena (if you have this problem, please check your power); The voltage should not be higher than 5V, otherwise the main chip and the amplifier IC and related components will be damaged. Please pay attention.\u0026lt;br\u0026gt; 3) Audio output: 3P block OUT audio output can be modified for external power amplifier, the middle is audio ground, left and right are L and R respectively.\u003cbr\u003e\u003cbr\u003e• It adopts 5.0 Bluetooth DC3.7V to 5V power supply, and undergoes secondary development processing through peripheral hardware. The maximum power can be configured to reach 10W (5W*2).\u003cbr\u003e• Can be modified for external power amplifier (from the 3P block OUT audio output external).\u003cbr\u003e• Micro power control.\u003cbr\u003e• Hands calling and external buttons.\u003cbr\u003e• Power supply: DC voltage (3.7 to 5V). The current should be 1.5A to 2A or higher.\u003cbr\u003e\u003cbr\u003eModel: Sanpyl0o17tqgdx6","brand":"Sanpyl","offers":[{"title":"Default Title","offer_id":52346812825882,"sku":"MCAB085DQN84S","price":25.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0965\/6772\/2266\/files\/61aZ7bMQ5tL.jpg?v=1781271709","url":"https:\/\/craftedyogi.com\/products\/bluetooth-amplifier-board-aux-audio-input-power-amplifier-board-37v-to-5v-25w","provider":"Craftedyogi","version":"1.0","type":"link"}
