The SJ2088POE baseboard offers full 802.3af, Class 3 PoE compliance with 1000BASE-T speeds. The SJ2088POE baseboard has three on-board cameras which implement stereo and RGB vision, piped directly into the DepthAI SoM for depth and AI processing. The data is then output to a host via USB 3.1 Gen1 (Type-C) or via 1000BASE-T ethernet connection. Ther SJ2088POE board exposes boot selection switches, allowing the end user to boot the BW2099 module from USB or the on-board eMMC or NOR flash.

The SJ2088POE accepts power input from any 802.3af, Class 3 PoE circuitry. So this for example includes any/every POE UniFi Switch (e.g. US-8-150W) and any other standard POE switch and/or 802.3af POE injector. Power consumption is typically 5W, leaving ~7.5W available if active lighting is desired additionally over POE/etc.
If an outdoor rated POE switch is needed, one option is the EP-S16.
Interfacing with the DepthAI SoM is also possible with BW2098POE connector pads J5 which expose BW2099 auxiliary I/O. This header is Amphenol/FCI 20021121-00010T1LF or equivalent. Please refer to the schematics for pinout information.
The reset button resets the Luxonis DepthAI BW2099 SoM only. The 5V LED indicates 5V power is present on the BW2098POE. The PG LED indicates “power good” from the DepthAI BW2099 SoM. The “RUN” LED indicates that the DepthAI SoM 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.
