PoE Board

../_images/BW2098POE_up.jpg

Overview

The POE Board offers full 802.3af, Class 3 PoE compliance with 1000BASE-T speeds, along with user-selectable external power from a 5V barrel jack. The Luxonis OAK-FFC-IMX378 12MP RGB camera module can be connected via the 26-pin FFC interface, which exposes a 4-lane MIPI CSI-2 channel directly into the Myriad X on the OAK-SoM-Pro (System on Module) for processing. Data can also be streamed to a host via USB 3.1 Gen1 (Type-C). Finally, the PoE Board exposes boot selection switches, allowing the end user to boot the OAK-SoM-Pro from USB or the on-board eMMC or NOR flash.

Getting started

Note

For more information on how to start with POE devices, check our guide Getting started with PoE.

The PoE Board accepts power input either from a 5.5m x 2.1mm barrel jack (5V +/-10%) or from the RJ-45 connector upsteam from the 802.3af, Class 3 PoE circuitry. A jumper near the MIPI FFC connector allows for user selction of the input power source. Booting can be accomplished from either the USB interface or from the eMMC or NOR flash on the OAK-SoM-Pro, and boot selection is configured with the DIP switch bank near the barrel jack connector. With the OAK-FFC-IMX378 camera and the OAK-SoM-Pro running inference, power consumption is typically 3.3W.

Interfacing with the OAK-SoM-Pro is also possible with PoE Board connector pads J5 and J8, which expose OAK-SoM-Pro auxiliary IO and OAK-SoM-Pro Quad SPI, respectively. These headers are Amphenol/FCI 20021121-00010T1LF or equivalent. Please refer to the schematics for pinout information.

The reset button resets the OAK-SoM-Pro only.

The 5V LED indicates 5V power is present on the PoE Board. The PG LED indicates “power good” from the OAK-SoM-Pro. The “RUN” LED indicates that the OAK-SoM-Pro is not in reset.

Caution should be taken when handling any PoE circuit board. Do not directly touch the circuitry as potentials upto and exceeding 57V may exist. Always use electronics handling best practices.
