{"title":"5V 1.8A Isolated Output PoE Module Works with Raspberry Pi 3 B+","handle":"5v-1-8a-isolated-output-poe-module-works-with-raspberry-pi-3-b","url":"/products/5v-1-8a-isolated-output-poe-module-works-with-raspberry-pi-3-b","description":"An isolated Power over Ethernet (PoE) module that extracts power from the Ethernet cable's centre taps and outputs a regulated 5 V at up to 1.8 A. The built-in isolation transformer ensures there is no direct electrical connection between the Ethernet side and the 5 V output — important for safety in certain installations and environments.\n\nThis module is well suited to the Raspberry Pi 3 Model B+, which exposes the PoE centre-tap pins on a header. Connect with female-to-female jumper wires, then route the 5 V output back to the Pi's power pins. At 1.8 A, it comfortably powers a Pi 3B+ for most use cases (typical draw is ~0.7 A without USB accessories).\n\nKey Features\n\n\n5 V 1.8 A Output – Regulated DC from standard PoE infrastructure\n\nGalvanic Isolation – Transformer-isolated for safety and noise reduction\n\nSimple Wiring – Four input wires from Ethernet centre taps, two output wires for 5 V\n\nRaspberry Pi 3 B+ Compatible – Connects directly to the PoE header pins\n\n\nSpecifications\n\n\nOutput Voltage – 5 V DC regulated\n\nOutput Current – Up to 1.8 A\n\nIsolation – Galvanic (transformer-isolated)\n\nInput – PoE centre-tap wires (4 wires)\n\n\nIdeal For\n\nRaspberry Pi deployments requiring electrical isolation\nIndustrial and outdoor PoE installations\nRemote IoT devices and sensors\nNoise-sensitive measurement systems\n\n\n\nTip: Don't need isolation? The 5 V 1.5 A Non-Isolated PoE Module is more compact and cost-effective.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5943,"title":"Default Title","sku":"AF-3848","price":32.69,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
