| Note | ① USB 3.0 is equivalent to USB 3.2 Gen1 ② There's PoE header only on the Raspberry Pi official IO board without PoE circuit, that means additional PoE module is required for the official IO board to enable PoE feature. Unless otherwise specified, the PoE feature here stands for integrating 802.3af-compliant PoE circuit (5V/2.5A). |
