Hi Mychaela, A bare board would do in theory, as I have a power supply that can provide up to 1.5A (should be sufficient) on any voltage from 1.5 to 12V. Soldering the + and - to the board should be no big deal. Regarding the antenna connector, I don't have one at the time, but SMA to MS-147 is in stock on mouser, so acquiring one will be possible. > > It's really great to see this project develop, and to get such > > detailed status reports and such; thanks so much Mychaela, as ever, > > for all your work.
