the alpha board looks very promising
But back to the topic:
We are a bunch of amateur astronomers and are developing an open source / open hardware and quite powerful telescope control system called openDrive.
<- high speed goto demo with our alpha motor driver board
<- slow speed up and down of a Escap P530 motor
<- our forum (unfortunately mostly in German, but google.translator can help if needed)
<- our wiki
The hardware design is supposed to be modular, so different CPU boards could be used for different processing power demands.
<- Some pictures of the pcb stack.
SPI is used as the interface between the CPU board and our motor driver board.
Currently we are focused on a Cortex CPU but the rasberrypi board could really become an alternative
It would bring a great amount of possible uses like USB-webcam auto-guiding for example, not to talk about all the other advantages having a real os with a network stack behind...
So - we really are looking forward to get our hands on your new linux board.
Question: Do you have info about boot capabilities of it at temperatures below 0°C ?
We could build a heater around it, but without it would be nicer of course.
