About
The Cordillera PCB is an open design PCB heavily based on the Alice PCB. The only breaking change is the USB connector which renders it unusable on most Alice cases.
- STM32F072 controller
- USB C connector mounted at the top
- ESD, over voltage, and over current protection circuits
- Dual common cathode diodes instead of single ones
- Backlight, single color
- Fancy "press to reset, hold for bootloader" reset circuit
Dependencies
Symbols and footprints used are from my KiCad library
Notes
- Original Alice uses USB Mini, so this PCB may be incompatible with some Alice cases

Questions
How big is the Cordillera PCB?
It measures 337.2 × 122.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cordillera use?
209 parts, built around the SRV05-4, XC6206P332MR, BAV70 and SMF6.0CA. 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 Cordillera KiCad files?
From the coarse/Cordillera repository on GitHub, at the commit this page was made from: the board is Cordillera.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cordillera design in my own project?
Its repository states no licence, so its author keeps all rights: ask coarse before reusing the design.
