The PBX-BB rev5.2 is our newest breakout board for the [[BeagleBone]]. It was designed to work with the LinuxCNC derivative, [http://www.machinekit.io Machinekit]. It features 16 total outputs and 8 inputs, all software mappable to whichever signals you need. The PBX-BB rev5.1 was redesigned to address pin conflicts that prevented the use of the direct LCD control built into the Beaglebone. You can now piggy back many of the popular LCD panels, such as the LCD4 and LCD7 capes from 4D Systems, as well as the BB-View capes from Element 14.

The PBX-BB is the new  CNC breakout board for the [[BeagleBone]].

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.

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 PBX-BB rev5.2 is our newest breakout board for the BeagleBone. It was designed to work with the LinuxCNC derivative, Machinekit. It features 16 total outputs and 8 inputs, all software mappable to whichever signals you need. The PBX-BB rev5.1 was redesigned to address pin conflicts that prevented the use of the direct LCD control built into the Beaglebone. You can now piggy back many of the popular LCD panels, such as the LCD4 and LCD7 capes from 4D Systems, as well as the BB-View capes from Element 14.
