Product Description
PoE+ (IEEE 802.3af/at) power module designed as a HAT (Hardware Attached on Top) for compatible ARM single-board computers. Converts 48V PoE to regulated 5V/4A output, providing up to 20W — enough for the SBC and connected USB peripherals.
Eliminates the need for a separate USB-C power adapter. Run your SBC from a single Ethernet cable carrying both data and power.
Features:
• IEEE 802.3af/at compliant (PoE+)
• Regulated 5V / 4A output (20W max)
• Integrated cooling fan (temperature-controlled)
• Pass-through 40-pin GPIO header
• LED power indicator
Requirements:
• Compatible 40-pin ARM SBC with PoE header pins
• PoE-capable switch or injector (802.3af/at)
