Repository Content

documents/:

• Contains test reports, data sheets and manuals for the WARP Charger itself and used components

firmwares/:

• All released firmwares as well as their .elf files used for decoding stack traces and further debugging

hardware/:

• Contains KiCad project files for some custom PCBs used in the WARP Charger

label/:

• Scripts and other files used to create and print the type label sticker

manual/:

• LaTeX source and used resources for the manual

warp-charger.com/:

• The source of the WARP Charger web site (this site is deprecated, the old hand-written html site has been moved to a wordpress)

Firmwares

The firmwares folder contains all released firmwares as bin files. These can be flashed using the web interface or over USB using https://github.com/espressif/esptool/ at offset 0x1000. The folder also contains the ELF files with debug information.

Hardware

Parts of the hardware are designed with the open source EDA Suite KiCad (http://www.kicad.org). Before you are able to open the files, you have to install the Tinkerforge kicad-libraries (https://github.com/Tinkerforge/kicad-libraries). You can either clone them directly in hardware/ or clone them in a separate folder and symlink them into hardware/ (ln -s kicad_path/kicad-libraries project_path/hardware). After that you can open the .pro file in hardware/ with KiCad and from there view and modify the schematics and the PCB layout.
