Raspberry Pi can flash the AVR, using avrdude with LinuxSPI support and inverted GPIO 17 as reset.

avrdude.conf configuration entry:

text

programmer 
  id       = "linuxspi";
  desc     = "Use Linux SPI device in /dev/spidev*";
  type     = "linuxspi";
  reset    = ~ 17;
  baudrate = 40000;
;

avrdude Usage to flash firmware:
avrdude -p m328p -P /dev/spidev0.0 -c linuxspi -U flash:w:firmware.hex

avrdude Usage to set fuses:
avrdude -p m328p -P /dev/spidev0.0 -c linuxspi -U lfuse:w:0xe2:m -U hfuse:w:0xd9:m -U efuse:w:0xfd:m

Questions

How big is the SolarCamPi PCB?

It measures 65 × 30 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SolarCamPi use?

54 parts, built around the ATMEGA328P-AU and DMP3099L. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the SolarCamPi KiCad files?

From the Manawyrm/SolarCamPi repository on GitHub, at the commit this page was made from: the board is pcb/solarcampi.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the SolarCamPi design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
