About this project
We were evaluating BeagleBone Black and Raspberry Pi for low cost control systems when we discovered that the modules, as shipped, were fundamentally unusable for anything other than connecting to your PC and programming.
For instance, some of the cautions listed in the BeagleBone Black Systems Reference Manual are:
"NOTE: Do not connect 5V logic level signals to these pins or the board will be damaged.
NOTE: DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.
NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH."
Since we were required to provide some kind of voltage isolation in order to connect the BeagleBone Black to any external devices, we figured everyone else would need some form of isolation as well in order to use BeagleBone Black in the real world.
An additional problem we discovered was that BeagleBone Black's default operating mode utilized many of the pins present on the I/O connectors and these were not available for general use without extensive operating system changes.
We also found that the Raspberry Pi has an extremely large user group and support. This has allowed people to develop a tremendous amount of software for various applications. However, like the BeagleBone Black, it is limited in its real world expandability out of the box. We wanted to allow existing users of Raspberry Pi to use BeagleBone Black like a Highly Intelligent Super I/O to expand their projects into real world applications. Additionally, this gives Raspberry Pi programmers a platform to easily port their routines to BeagleBone Black.
We created a multi-tool: an all-in-one 3.5" peripheral voltage isolating motherboard for the BeagleBone Black and Raspberry Pi Model B computers and expanded out and isolated all of the default configuration pins that were not being used by BeagleBone Black internal resources. We also created two different on-board communication links between Raspberry Pi and BeagleBone Black for advanced control functions. Now you are able to run both modules individually or simultaneously in the real world.
The MotherBone™PiOne™ provides:
- Multiple on-board switching power supplies powering Raspberry Pi and BeagleBone Black and the on-board high-powered USB hub
- Power isolation to protect BeagleBone Black and Raspberry Pi I/O pins
- Extensive high powered I/O for real world projects

How do I get started with MotherBone™PiOne™?
You will need to provide either a BeagleBone Black or Raspberry Pi Model B. Then follow this video to watch how easy it is to get started!
Current State of the Project
We are asking for financial support in order to start up production and set up a dedicated manufacturing line at our shop in Oregon City, Oregon. This will provide a constant and consistent supply of MotherBone™PiOne™ modules to the programming community. Having been in the electronics business for many years, we at APlus Mobile are dedicated to bringing manufacturing jobs back to the USA.
- Following funding, we will order the first set of materials which takes approximately four weeks to receive. Concurrently, we will set up a dedicated manufacturing cell with tooling at APlus Mobile's shop in Oregon City, OR. (Completed June 2014)
- Once the cell is set up, we will run the first batch of MotherBone™PiOne™ modules for the EARLY ADOPTERS. The first batch will be produced in approximately four weeks. (First shipment July 2014)
- This will allow us to go into continuous production to fulfill rewards for the PRODUCTION and PHASE 2 BACKERS and beyond. We have designed the production process to be scalable depending on demand. (Weekly shipments to fulfill rewards starting in August 2014)
Take DIY Off Grid Energy Control to the Next Level by Rob Cermak
Off grid energy control just got easier... Is there a better way to get more control [of my DIY Off the Grid System]? The Raspberry Pi would be a good next step, but I need a rock solid solution. Introducing the MotherBone™PiOne™ motherboard from APlus Mobile, Inc.
There are an amazing amount of features on this board. Pair the motherboard with a Beagle Board Black (BBB) and you have an amazing low power supply and controller that can snuggle right into a 24V off grid power system.
APlus Mobile has been in business since 2004 and has had success supplying DC-powered computers for use in communications networks, robotic vehicles, boats and aircraft. We have designed and manufactured various types of computers and peripherals that are installed in trash truck cabs, run on solar power for oil exploration, packed in suitcases for field deployment to remote locations, and others.
We support education through our current sponsorship of Embry Riddle Aeronautical University and their 2014 Maritime RobotX autonomous boat. See the boat in action with the following link:
We would like to continue supporting education, but this time on a smaller scale, by making open sourced hardware tools more accessible to everyone.

Risks and challenges
We have significant experience in product development and high volume manufacturing for products of this type so there is little risk in our ability to manufacture this product in sufficient quantity to meet demand.
We have also value engineered the product with component availability in mind, however, component availability lead time is always a risk with any manufactured product.
We will keep everyone aware of any lead time changes due to any reason.Learn about accountability on Kickstarter
