Voltage shifting
In detail, what we need to fix are two problems: one is how to power the ZMotion device, and the other is how to make them be able to talk to each other. There are many solutions to solve these problems; however, most of them will involve hardware assembling and require necessary electronic design experience.
Here, in this chapter, we are considering a ready-to-use solution, which is more suitable for users without an electronic background (for example, if you are from computer science). The trainer board from Tincan Co. Ltd. (http://www.tincantools.com/) has been designed to work with BeagleBoard-XM and includes a 1.8V to 3.3V bi-directional converting function. The selling price is only $59, which should be affordable for most users. We may also need to purchase another useful device—the breadboard—which is very helpful in rapid prototype development. A breadboard doesn't cost much, and is easily available at eBay, Amazon, or a local electronics shop.
