Is there a schematic available for the latest R7 USB board? The latest one on github looks like R6. A PDF version would be great if possible.

Thanks!

Actually R7 was an experimental revision based on this thread in the forum, where the request was to add a mosfet to drive one of the serial lines into the FTDI chip.

That turned out to be redundant and "R7" always shipped with a short 0-ohm resistor instead, equivalent to R6 in terms of schematic/wiring.

The new "R6" is also equivalent to the old R6 (and R7) but adds a Reset button. Otherwise the schematic is the same as the R6 before R7 (lol).
The change being only functional and not behavioral, I wanted to revert to the R6 and keep it that way.

Sorry about any confusion. I should update the photos to reflect that, and maybe add a paragraph to document the shift in revision numbering.

Thanks for the update Felix. The  Moteino USB boards that I just received are marked R7 and do have the 0 ohm resistor added as you mentioned.

I don't see any board files for the  R6 (or R7) Moteino USB on GitHub. Any chance of adding those?

There's the R5 USB posted, pretty much the same but has HW radio, what are you trying to do?

I was just wanting to have a copy of the schematic that matches my new R7 boards.
Thanks
