I looked again and still don't see any way to use this as an h-bridge. The pins are all logic level.
Looks like the supply is unlimited at $239 each I looked at the documentations about how to program it. here is the basic model: They supply a custom Ubuntu image on an SD card and it has all the software you need. The programming is done via a Jupiter Notebook. You connect your PC/Mac web browser to the notebook and can then run iPython interactively inside the notebook. I suspect you could also use a text editor to create a python program but they don't talk about that. They wrote a Python module that will load "overlays" (bit files) into the FPGA. These create peripherals that the ARM/Linux/Python system can see. The peripherals are things like GPIO pins, Interrupt controllers, video CODEC converters and so on. Then there is a Python module that will talk to the peripheral device. There is a way to create your own overlays but you are using Verilog or VHDL So you are not actually programming the FPGA in Python. You are loading some FPGA code then using Python to access what you loaded. The things you load are called "overlays" From what I read the average user will NOT be created his own overlays. A small bit of rocket science and magic is required to do that. They are using the FPGA is a peripheral device that can do any of a few dozen functions and is fast enough to do things like handle HDMI video bit streams At first I was excited that they might have found a way to use Python in place of Verilog and could synthesis a Python program into gates on an FPGA. That would have been revolutionary. But what they have done is found a way to add very fast hardware peripheral devices to the Arm chip and keep it general purpose How could this be used in a typical robot or machine tool? I'd say if your machine needed to input and process uncompressed HDMI video, this is the ticket. If a webcams just not giving you the video quality you need this might allow you to get high quality video directly into OpenCV and then you process it and send it out the 1000BaseT Ethernet all for only $239. And you don't need to mess with Verilog as the Python libraries are pre-written.
