CrossRoads:
You guys are missing the point - I'm looking for feedback on this commercialy available item that I can program and turn over for someone with minimal experience to be able to program newly built cards before they get assembled into a product. No PC involvement, no thinking, no chance to screw up a sketch.
No PC. Not looking to reinvent the wheel. Not looking to put a bunch of time into productizing Nick Gammon's hex uploader (tho that would be cool).
I'd just like some feedback on this item and its suitability for programming fuses to be like an Uno and upload a sketch, all via the ICSP header.
Thanks.
Something to think about, you could use the Little Leo board (minus the SD) with a 7805 regulator and a barrel jack. You could keep the USB on the board if you want. However, the bootloader sketch from Nick might need changed to work.
P.S. I have had great success using Nick Gammon's bootloader with an Uno.
