About this project

The Background

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.

The Solution

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

Easily realize complex projects through this Linux based control module

Funding

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.

Manufacturing

Manufacturing Flow Chart
Manufacturing Flow Chart
  • 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.

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.

FAQ

  • You're exactly right - the Raspberry Pi does what you would expect a $25 computer to do, but that makes it inherently unusable for real world I/O expansion as a control system such as for automotive or home control. If Raspy users didn't have a BeagleBone, they could use the MotherBone™PiOne™ for a robust power system, I2C 16-bit GPIO slave, high powered USB hub and also utilize the five relays. Additionally, they can use the Raspberry Pi Pass Thru Header to use standard Raspberry Pi peripherals simultaneously. So without the BeagleBone Black present, there is still a lot of expanded capability using the MotherBone™PiOne™ for Raspberry Pi users. However if Raspberry Pi users do use the BeagleBone Black on board, it provides a highly intelligent Super I/O capability that unburdens the Raspberry Pi user interface and Operating System. Reading through the System Reference Manual, however dry and arduous it may be, will yield a lot of these "hidden" features of the MotherBone™PiOne™.

  • Volume drives price. The actual retail price should be under $200. If we could get large enough order volume it could be sold for much less, however in the hundreds it gets into the $200 range. Please remember that we are trying to set up a new Oregon based manufacturing line with this funding, which is why the rewards in this campaign are more expensive. Local manufacturing is beneficial for a constant and consistent supply of MotherBone™PiOne™ modules on the market. Unfortunately, if this funding is not successful, it is unknown if this module will ever be available.
