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.

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.

-# Burn our custom [https://drive.google.com/file/d/0B5vTOfoZpyAXVWk0NWFPQ3E3R00/edit?usp=sharing Machinekit Iso Image] to an 8GB Sandisk MicroSD Card using [http://sourceforge.net/projects/win32diskimager/ Win32DiskImager]
-# Install the MicroSD card, plug the BBB ethernet connector into your network, hold down the SD boot button, and apply power. The first time the image boots, it can take up to 5 minutes.
-# The Machinekit image uses DHCP. Run a port scanner such as [http://www.advanced-ip-scanner.com/ Advanced IP Scanner] to find the ip address of the BBB (or 'arp -a' from a command prompt). It should have only two ports open (80 and 22).
-# Install [http://sourceforge.net/projects/xming/ XMing] and [http://www.putty.org/ Putty].
-# Turn on X11 forwarding in Putty and connect to the BBB.
-#: Username: linuxcnc
-#: Password: linuxcnc
-# Launch LCNC by typing 'linuxcnc &' into the shell. The LCNC software, while running on the BBB, will forward its window onto your PC. Choose the PBX-BB configuration. On future sessions, simply launch LCNC with the PBX-BB config by using the 'last configuration' switch 'linuxcnc -l &'.
-# Use [http://winscp.net/ WinSCP] and [http://notepad-plus-plus.org/ Notepad++] to edit the config files. When you choose 'edit' from WinSCP and allow WinSCP to open the file in Notepad++, whenever you make a change and save the file, WinSCP will automatically re-upload the changed file to the BBB.
