MOTOR
A `generic' cable from eBay (these vary)
Factory Centre pair swapped A+ RED A+ RED A- GREEN A- BLUE B- BLUE B- GREEN B+ BLACK B+ BLACK
My generic cable has A- B- twisted at the motor (JST) end so not usable with my motor on this board without swapping the centre pair of cables (at either end).
For JST, just lift the plastic tooth and pull the cable out, very simple.
PORT
1 2 3 4 2B 2A 1A 1B B+ B- A- A+
MICROSTEPPING
Jumpers select the micro-stepping mode which will default to 32 microsteps/step for a DRV8825.
Schematic
The Schematic has a missing pull-up resistor of 100K on the SLEEP/RESET pins (named SLP) on each motor controller unit.
