ENC424J600 breakout board

Overview
This is a breakout board for Microchip's ENC424J600 100/10 Base-T Ethernet chip with unique MAC address. This is a spiffy little breakout board that probably works great, but we got tired of messing with the not-open-source Microchip TCP-IP stack. This could be put into production with a little testing, and an open source driver for FreeRTOS, etc.
PCBs are available for this one, but be warned that the HanRun jack will be hard to find (lately there are a lot of them on eBay). You might need to fly-wire it for testing, or write Seeed and ask for a jack.
