WARNING: Do not exceed the maximum specified current for these connectors.
WARNING: Do not connect power to the DC INPUT (P5) jack on the BeagleBone once mounted
on the BeBoPr. This will most likely damage the BeBoPr and/or the supply connected to the
DC INPUT.
Stepper Motor Connections
If the BeBoPr has the stepper driver modules on board, the four stepper motors connect to
J15, J16, J17 and J19. In that case connector J5 is hidden underneath the driver modules and
can not be used.
J15 – X-axis, pins 1&2 motor coil-A, pins 3&4 motor coil-B
J16 – Y-axis, pins 1&2 motor coil-A, pins 3&4 motor coil-B
J17 – Z-axis, pins 1&2 motor coil-A, pins 3&4 motor coil-B
J19 – E-axis, pins 1&2 motor coil-A, pins 3&4 motor coil-B
Stepper signals connector
J5 – all stepper signals are present on this connector. It connects directly to the 15 pin sub-D
connector of a TB6560-4V5 3A stepper driver board sold on e-Bay.
