Ah! I didn't quite twig that. Thankyou. Should I put that up in the first post?

Aye, there are a few small ones around. This is mostly a learning experience for me! Electronics is a hobby, and I have to learn by reading, and by cocking up. :) Plus, there's an element of fun with making something to fit exactly what I need. Gives me something to fiddle around with in the evening...

Ah, yes. I had seen that little table, alas, I was hoping! Level conversion is a pain for bidirectional lines, more than single-way. Guess it's worth seeing how small I can squish what's required, and work out if it's worth it. Again, thankyou for your thoughts :) For the sake of soldering on a few ...

Very true. Will have a little looksee. I can't see anything immediately in the module datasheet that says one way or the other, which is frustrating- but I guess firing off an email to HopeRF can't hurt. Not sure how good they are at responding, mind. It seems I've mixed up the wires for the NIRQ/NS...

Makes sense, Mike. May rig up a greenwire fix for now, and have a look at sorting the boards out before I order the next batch. I like nicely researched answers! Thanks again for taking the time to look it up. Guess it serves me right; there's quite a lot of people out there who seem to think that i...

Hello, thanks for your time in answering / questions. I was previously under the impression that the Atmel '328 chips, while only available (in arduino form) as 5v/16MHz and 3.3v/8MHz, are used in the Flytron and OrangeRX OpenLRS modules running at 3.3v and 16MHz. This would seem to be true, as the ...

The board is assembled, and runs as an Arduino. Bootloader took, as a Pro Mini 5v/16MHz (despite running on the 3.3v that is required by the radio module). The Arduino "blink" sketch runs just fine, and can operate the two LED's on the board with no issues. The circuitry is modelled on Fly...

Boards are in from the fab; Company used is OSH Park, look good- and are, of course, purple.

Assembly and testing tonight.

Well, the boards' been gone over a few times now, and a few minor changes made to improve clearances between tracks. They're also now on their way back from the manufacturer, and I've the components to populate a couple- it's amazing how much they charge for SMD components when you only want 10 or 2...

Hello, I am in the process of designing hardware to use the OpenLRS firmware; At present, it's in the very early stages- board design and checking. The concept is as follows; to, using the same board schematics as are available for another unit, produce the smallest possible footprint using the RFM2...
