For v2.0.3, you should wire the pins in the J16,J17,J18 headers directly to the pins on the corresponding side of the roboclaw - it is a direct 1-to-1 mapping all the way down, with no wires crossed.
Unless you have an older version of the PCB (v2.0.2 or earlier), wire the pins in the J16,J17,J18 headers directly to the pins on the corresponding side of the roboclaw - it is a direct 1-to-1 mapping all the way down, with no wires crossed. Use 16AWG wire (18AWG would also be fine)
