Setup
Flash micropython as per /main/micropython-bin, afterwards copy ubuf2png.py onto the ESP32-CAM with ampy -p /dev/ttyUSB0 -b 115200 put ubuf2png.py
Usage
This is WIP and will be moved to saving the PNG to a SD card directly soon.
Manual usage
Place an SD card into the SD-Card slot and run
ampy -p /dev/ttyUSB0 -b 115200 run boot.pyParts

Questions
How big is the Picsy hw PCB?
It measures 125 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Picsy hw use?
114 parts, built around the CH340C, ESP32-WROOM-32D, XC6206-1.2V and XC6206-2.8V. 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 Picsy hw KiCad files?
From the Jana-Marie/PICSY repository on GitHub, at the commit this page was made from: the board is picsy-hw/picsy-hw.kicad_pcb and its schematic picsy-hw/picsy-hw.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Picsy hw design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jana-Marie before reusing the design.
