> And it has PoDL (PoE equivalent) too! Though at 5V/250mA, I think this is for the board to power sensors, not the board to receive power itself.

I dug through some documentation, and yes, it's PoDL source only.

I'm still holding out for someone to make a pair of devices: A is ethernet + spe + PoDL source, B is ethernet + spe + PoDL powered. Hopefully for not a lot of money.




Specifically for adapting cat5 ethernet to SPE, I found this converter for example:

https://www.methodedatamate.com/10base-t-to-10base-t1l-media...

But it doesn't look like 'commodity' cheap - it's probably several times the price of the beagle...


I did find a couple media converters available for sale:

https://www.arrow.com/en/products/10base-t1l-mc/einfochips-l... at $85.75

https://botblox.myshopify.com/products/speblox-long at $175

https://www.ti.com/tool/DP83TD510E-EVM listed as $150, but $200 from Mouser

It's hard to buy the first one when this board is only a little more expensive and comes with everything else (even if I don't need the everything else).

If I had circuit design skills and patience, I'd try to whip something up using the 'back to back' PHY mode, in theory, you connect a 10base-T1L PHY up to a 10base-T PHY, setup the proper 'straps', put in the right passive components, supply power, and that's it; no microcontroller required.


Yes the Ti SPE chip they use here is available for <$10 or so on mouser etc, let's hope we see some modules.
