There are no user changes required on the v1 board
(which, by the way, is the only version in production – there is no second thing…)
There was a note on the wiki about needing to remove a resistor if you didn’t want to configure the motor Enable line to be active LO, but this is unnecessary if you use the patched .HEX file, or (more recently) use the grbl 0.7 release from the grbl github edge branch. That wiki text has since been removed because it caused more confusion than it cured. You can ignore it in the hard copy instructions, too.
