I've spent most of this weekend (about 14 hours of it) soldering 3 of these. It's an industrial 24V IO board for a client with Ethernet interface. 14 of the pins are programmable input, output, pull up/down, adjustable thresholds etc. I've already made two but I want more to check the networking stuff properly.
I can't post any code or actual circuits (because it's for a client) but the basic Ethernet code is mine and I'll publish it tweaked for a different board early in October.
The 39p direct form China Ethernet connectors with built in magnetics and LEDs seem to work fine !
