Nice board, small nits on v0.0.2

[Bwooce]

(nothing real, just nits)

• R3,R4 should be 10k (not specified, but SPI pull-ups)
• D1 should be a schottky diode like an SS14?
• J2 (USB) is labelled 3v3 which is true if the switch is set. is that why? so not an error, you use this as some kind of 3v3/usb supply in the field?

I'm keen to spin a few of these for TinyGS @ 433Mhz, combine them with an antenna like this 70cm Quadrifilar Helical Antenna, batteries and solar panel, and leave them to it.

Thanks for this board, I'm interested to know if you've tested further as I plan to spin one for myself and send some out into the world (like SA0PEJ, if he wants one, since he made a killer antenna).

Thanks,
Bruce

Hi @Bwooce! Sorry for not answering a month! Just read your bug report! Somehow it got lost in my mails.

R3,R4 should be 10k (not specified, but SPI pull-ups)

Yes.

D1 should be a schottky diode like an SS14?

Yes to avoid back-feeding voltage into the USB-Host (switch in "In" mode)

J2 (USB) is labelled 3v3 which is true if the switch is set. is that why? so not an error, you use this as some kind of 3v3/usb supply in the field?

• Either you can supply 5V from the USB-Host to the board or..
• ... use the connector something different. Then the board will supply 3.3V to the device you want to connect there.
