{"title":"3W Mini Audio Stereo Amplifier (W2.54)","handle":"3w-mini-audio-stereo-amplifier-w2-54","url":"/products/3w-mini-audio-stereo-amplifier-w2-54","description":"This compact stereo amplifier module from DFRobot features a 2.54mm pin pitch for easy breadboard and embedded use. It delivers 3W per channel with left and right stereo output, and includes a shutdown (SHDN) pin for switching between working and sleep modes.\n\nBy default, the module is in working mode when the SHDN pin is unconnected. Pulling SHDN low (0V) puts the amplifier into sleep mode, while pulling it high (5V) enables working mode — making it easy to control power consumption from a microcontroller.\n\nKey Features\n\n\nStereo Output – Independent left and right audio channels\n\n2.54mm Pin Pitch – Breadboard-friendly for easy prototyping\n\nSleep/Wake Control – SHDN pin for low-power sleep mode\n\nCompact Module – Small form factor for embedded applications\n\nNo Programming Required – Works directly with passive speakers\n\n\nSpecifications\n\n\nOutput Power – 3W + 3W\n\nPin Pitch – 2.54mm\n\nPower Supply – Up to 5.5V DC max\n\nSleep Mode – SHDN pin low (0V) = sleep, high (5V) = active\n\n\nIdeal For\n\nRobot voice systems\nDIY music boxes\nSound modification projects\nEmbedded audio applications\n\n\nPackage Contents\n\n1× 3W mini audio stereo amplifier module (W2.54)\n\n\n\nWarning: Do not exceed 5.5V input — overvoltage will damage the IC. Do not reverse the positive and negative poles. The negative poles for the left and right channels are independent and must not be connected together.\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3445,"title":"Default Title","sku":"DF-DFR0119-O","price":8.54,"on_sale":false,"in_stock":true,"available_quantity":119,"option1":"Default Title"}]}
