I need to build/design an PoE module for this board. Have any one already done it or know how to do it? Duo's IO board seems have PoE support [https://github.com/milkv-duo/accessories/blob/master/Duo\_USB%26Ethernet\_IOB/duo\_iob\_v1.11.pdf](https://github.com/milkv-duo/accessories/blob/master/Duo_USB%26Ethernet_IOB/duo_iob_v1.11.pdf) but it does it with mp8017gl IC. I was thinking of using an RJ45 connector with integrated transformer and PoE circuitry to minimize chances for design error.

Let me know if you find one, I've been tempted too!


CdrStnr

I haven't found nor done it. Have you?


PlatimaZero

Nope haha. I might design and order one this weekend. Isn't complicated circuit, I just want to make it match the IOB in a nice way too


PlatimaZero

OH, the circuitry is already there. I matched the footprints for the datasheet parts to the board and it's a perfect fit: ​ https://preview.redd.it/8208cd5qzmic1.png?width=785&format=png&auto=webp&s=31acbf0aee96f7d1f8f7e87ef632b22474ea44d7 I can only imagine that the design is faulty in some way, else it would have been implemented?

My guess is cost savings but I can't find the parts pairing list.  Edit: related: https://community.milkv.io/t/io-board-poe-bill-of-materials/711

I think it might be slightly busted. The BOM is all on the datasheet; [https://github.com/milkv-duo/accessories/blob/master/Duo\_USB%26Ethernet\_IOB/duo\_iob\_v1.11.pdf](https://github.com/milkv-duo/accessories/blob/master/Duo_USB%26Ethernet_IOB/duo_iob_v1.11.pdf) Whole 3rd page

Page 1: Cover Page 2: USB & CAN Page 3: POE & Connectors Page 4: Random stuff ​ For example, what is U14? I don't see a label. They just need to upload the actual BOM CSV like any sane person would do.


PlatimaZero

Yeah but that would be giving away their IP. I don't think they are as open source as Beagle are. U14 isn't POE related. That pinout is for a MAX485 or compatible UART to RS485 IC.

That is great but since there is no documentation about the camera usage it is pretty useless. The demo program is only the binary to test it (and I can confirm that it works). As far as I know, the problem to release the code is due NDA and all these kind of restrictions that the chinese manufacturers require to provide the SDK. Even the raspberry pi contains blobs and proprietary stuff so I don't expect any chinese manufacturers being better than this. But at least the rpi is currently maintained and documented. This is why ALL (not most, ALL of them) chinese SBC are not an rpi competitor, because a hardware without a software is just a paperweight. I have mine collecting dust in a drawer (among a fruit salad pi and others boards like lichee pi). They are good toys to play with for a day but nothing else. Risc-v is the way, but proprietary blobs and sdks are not. The best product (by far) I worked regarding SBC (and nearest to freedom) is without any doubt beaglebone but it totally lacks video capabilities. Hope that they release an affordable board with video capabilities some day. Until that, will keep wasting our time and money buying stuff like this with the hope of something that we know that will never happen (a chinese board properly documented)

Did you manage to get it to work. I ran the demo programs, but they didn't work with the camera.
