Description:
The PBX-BB is the new CNC breakout board for the BeagleBone. It works perfectly with Charles Steinkuehler's Beaglebone port of LinuxCNC. It features 15 total outputs and 5 inputs, all software mappable to whichever signals you need. The PBX-BB features the same RF isolation circuitry found on the popular PBX-RF, protecting the Beaglebones' sensitive 1.8V and 3.3V circuitry from potentially damaging noise and spikes that can come from high voltage stepper motor drives.
The PBX-BB has 5x PBX-Headers (Figure 1) for easy connections to our stepper drivers and relay boards. Additional signals are present on the screw terminals for driving up to 5 motors and 4 relays.
New on the PBX-BB is a 5V/2A switching regulator that accepts voltages up to 76VDC. The efficiency of a switching regulator reduces heat. The 5V rail is bussed out to the PBX-Headers just like our other breakout boards, allowing you to drive the logic supply of the drivers from a single power source.
