10. MODIFICATION

If the version number of your PCB is v1.0, you have to
make a small modification to make it work with versions
above it.

You only have to connect pin row 6 to pin row 8 with some
wire on both headers as seen on the image to the left.
You also have to connect the pins next to eachother with
some solder.

That’s it!
