PCBs have left Wuhan, ought to arrive in New York on Tuesday.

travisgoodspeed commented 6 years ago

Boards made it to New York early, but I wasn't home to receive them. Please send me an email reminding me of your address if you'd like some shipped your way on Monday.

Boards arrived, but the first prototype reboots before getting to the time. The bootloader still works, so I'm hoping its a soldering mistake and not a wiring problem.

I'll solder another tomorrow, and also try for a better software diagnostic. (The display clears before the POST.)

We're ordering parts to assemble some boards at GSG. Based on the note that came with the printed BOM, you might find this handy: https://github.com/mossmann/kicad-bom-scripts

@mossmann Be sure to order GW20 parts. I'll be sending some of those boards shortly.

mossmann commented 6 years ago

Can you please invite @yhetti (Taylor of GSG) so that he can access the design files directly?

travisgoodspeed commented 6 years ago

@mossmann Invite to @yhetti has been sent.

Confirmed the non-RF portions of the PCB layout for GoodWatch20. I'll close this issue when I solder the RF sections and transmit a carrier wave.

The Yageo chip antenna is far too tall to fit under the LCD. I'll do a horrifically out of band wire antenna for now, but other antenna solutions would be welcome.

I'm now wearing the first complete GoodWatch20, transmitting my callsign in Morse on 70cm at the touch of a button! Closing this issue and opening a new one for the GW21 after writing up the hardware errata.
