{"title":"386AMP Audio Amplifier Module (Arduino compatible)","handle":"386amp-audio-amplifier-module-arduino-compatible","url":"/products/386amp-audio-amplifier-module-arduino-compatible","description":"The DFRobot 386AMP audio amplifier module is based on the LM386 low-voltage audio power amplifier IC. With a fixed voltage gain of 26 dB (20× amplification) and static power consumption of only 24 mW at 6V, it's well suited for battery-powered applications.\n\nConnect a microphone, MP3 module, or other audio source to the input, and the amplifier drives the included speaker. It's a straightforward way to add audio output to Arduino projects, robots, or interactive installations.\n\nSpecifications\n\n\nAmplifier IC – LM386\n\nPower Supply – 4–12V DC\n\nVoltage Gain – 26 dB (at 6V, 1 kHz)\n\nOutput Power – 325 mW (8Ω load at 6V), 500 mW peak\n\nBandwidth – 300 kHz\n\nStatic Power Consumption – 24 mW (at 6V)\n\nBoard Size – 45 × 30 mm\n\n\nKey Features\n\n\nLow Power Consumption – Suitable for battery-powered projects\n\nArduino Compatible – Simple analogue input, easy to integrate\n\nSpeaker Included – Ready to use out of the box\n\n\nIdeal For\n\nAdding audio output to Arduino and microcontroller projects\nRobot voice interaction and sound effects\nAmplifying signals from microphone or MP3 modules\n\n\nPackage Contents\n\n1× 386AMP audio amplifier module\n1× Loudspeaker\n\n\nResources\n\nDFRobot Wiki\nSchematic (PDF)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":14097,"title":"Default Title","sku":"DF-DFR0064","price":20.95,"on_sale":false,"in_stock":true,"available_quantity":32,"option1":"Default Title"}],"documents":[{"title":"386 Amp%20 Module%20 Sch%20 Dfr0064","type":"datasheet","type_label":"Datasheet","url":"https://image.dfrobot.com/image/data/DFR0064/386AMP%20Module%20SCH%20DFR0064.pdf","link":false,"file_extension":"PDF","description":"Linked from product description"},{"title":"Supplier page — dfrobot.com","type":"supplier_description","type_label":"Supplier Description","url":"https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD0CMBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--074bb0174f3db6f0e01ceba73398e924095680c2/386amp-audio-amplifier-module-arduino-compatible-dfrobot-com-2026-05-13.pdf","link":false,"file_extension":"PDF","file_size":620555,"description":"Snapshot of https://www.dfrobot.com/product-165.html (captured 13 May 2026)"},{"title":"DFR0064 386amp audio amplifier module schematics v1.0","type":"schematic","type_label":"Schematic","url":"https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDHEEDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--e60ccb834b51e9cfb02a241386d82a7e1fadd477/DFR0064_386amp-audio-amplifier-module_schematics_v1.0.pdf","link":false,"file_extension":"PDF","file_size":38679},{"title":"DFR0064 386amp audio amplifier module datasheet v1.0","type":"datasheet","type_label":"Datasheet","url":"https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDHUEDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--71c232e773406a1de37cba899ad76a6f5e71cc0e/DFR0064_386amp-audio-amplifier-module_datasheet_v1.0.pdf","link":false,"file_extension":"PDF","file_size":270761}]}
