Hi Brad,
It looks as though most of the interest (and therefore) support of these boards waned quite some years ago. I thought this would mean that it was a proven design and all of the bugs had been worked out - that doesn't seem to be the case! Having said that - my three embeddedtronics boards worked at 24V, so you may find that you have no problems. I found it quite annoying that the company didn't have an updated BOM, so I had to make an educated guess at some component values.
I have actually fabricated one of the original UHU boards (a homemade etched board). I've stuffed it, but am having problems communicating with the UHU chip so need to spend time troubleshooting that. I wanted to see if the original board was any better at 48V. More to come!
To be honest, with the time and money I've spent in components, the Geckos are looking better and better. But I'm an engineer by trade, so I quite like the problem solving and homemade aspect of this hobby. Plus I hate it when something is not working - I need to figure out why!
