Product overview1. The raspberry pi poe hat is a power over ethernet poe accessory for the raspberry pi 3b 4b. Compared to its predecessor raspberry pi poe hat, it features better cooling effect, implementing the 802.3Af at standard with 5v dc 4a larger power output, providing enough power for both raspberry pi 3b 4b at max load and other peripherals at the same time. 2. By using this small hat and some proper 802.3Af at-compliant power sourcing equipments, it is possible to provide both network connection and power supply for your raspberry pi in only one ethernet cable.Specification1.
