@gonzopancho – I’d like to test out pfSense on my (two) EspressoBIN boards when they arrive as well.
My boards are 2GB (I believe that many are 1GB, so it might make a difference performance wise).
I do not know yet if my boards have eMMC, but I do plan on attaching a 2.5″ WD Red harddisk (especially for logging).
I’ve ordered a USB3-to-Ethernet adapter, which works with Armbian; I don’t expect that it will work with pfSense, but since it already works with Armbian, the source code for the driver must be availble – that might make support possible.
(I’ll also be ordering a Marvell based Mini-PCIe-to-4-port-SATA adapter).
