That looks like a raspi killer, but whats an eMMC memory, because I sure don't see a socket for a micro-sd card. > > ...if it works out, it may be a good midway point between the ARM > based SBCs and a full x86 machine. I agree, except for the system memory. Soldered to the board flash memory bothers me, a lot. If it didn't, I would have used my card to put some postage on its even better equipt 4Gb dram and 32Gb of e-MMC. I have 2 of the original D525MW boards, one of them is still software stepping a 4 axis micro-mill.
