Great to see SPE (ethernet) here, this is going to be an important IoT/industrial standard IMHO, and I'm not aware of any other hobbyist options. And also it seems they haven't chosen one of the seemingly proprietary/industrial/expensive connectors, which is great too.
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.
- jacknews 4y agoYes the Ti SPE chip they use here is available for <$10 or so on mouser etc, let's hope we see some modules.
- jacknews 4y agoSpecifically for adapting cat5 ethernet to SPE, I found this converter for example: https://www.methodedatamate.com/10base-t-to-10base-t1l-media-converter-adapter/ 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...
- toast0 4y agoI did find a couple media converters available for sale: https://www.arrow.com/en/products/10base-t1l-mc/einfochips-limited https://www.arrow.com/en/products/10base-t1l-mc/einfochips-l... at $85.75 https://botblox.myshopify.com/products/speblox-long https://botblox.myshopify.com/products/speblox-long at $175 https://www.ti.com/tool/DP83TD510E-EVM 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.
