I have Nick’s assembled two board solution also along with one set of the bare boards and his parts list.
I have to say that Nick could have done a better job of soldering on his assembled boards as I had to touch up a number of the solder joints and I changed out a couple of the connectors to more reliable connectors.
As far as Nick’s firmware goes, it was really designed for two horizontal thrusters and one vertical thruster. Since the more comprehensive thruster configurations are of the vectored type with two vertical thrusters, Nick’s firmware would have to have a major overhaul to control such a vectored configuration. I worked with Nick’s firmware a lot, consider it to be very basic, and no where as capable as Rusty’s navigation control firmware.
