Thanks for the info. looks like it would require software to get the same FPGA used in both (Lattice ICE40) to report X5 instead of x3. There is a system reprogramming header on the PCB, but this stuff is way out of my league.
Whats up with the CART pin(B32)? it has a connection to the FPGA instead of the GROUND plane. why would the cart do this?
