PBX-BB


Model: PBX-BB BeagleBone Breakout Board

Breakout Board Specs:

  • BeagleBone Black Compatible
  • Screw Terminals or 5x PBX-Headers
  • Isolated Inputs and Outputs
  • 15 Outputs and 8 Inputs
  • Integrated 5V/2A Logic Supply Regulator
  • USB Powered BeagleBone

Description:

The PBX-BB rev5.1 is our newest breakout board for the BeagleBone. It works perfectly with Charles Steinkuehler's Beaglebone port of LinuxCNC. It features 15 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 has 6x PBX-Headers (Figure 1) for easy connections to our stepper drivers and relay boards. Input signals now make use of 10 pin IDC headers as well.

New on the PBX-BB rev 5.1 keeps the tried and true MAX5090 based 5V/2A switching regulator that accepts voltages up to 76VDC. 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.
