The lamobo-r1 board, sometimes called the BPI-R1 but not labelled as such on the PCB, is meant as a A20 based router board. As such the board comes with a built-in switch chip giving it 5 gigabit ethernet boards, and it has a large empty area on the pcb with mounting holes which will fit a 2.5 inch harddisk. To complete its networking features it has a Realtek RTL8192CU for WiFi 802.11 b/g/n.

Sorry that I missed it :/

It looks mostly fine, I just have a minor question / comment below.

Have you used the default OPPs and it turned out to be unstable, or is it just some copy / paste from the FEX file?

Thanks!

Just copy paste from the fex file, let me know if you want a new version with the opp-s removed.
