QMK compatible PCB replacement for Cherry G80-1800

The board has been prototyped and works as intended, while fitting most G80-1800 housings. Rev 1.1 and later should fix all tolerance issues, and fit all G80-1800 (and as far as I know also G81-1800) enclosures. I can, however, not guarantee perfect operation of the PCB or compatibility with every enclosure variation - if you encounter any issues, please let me know. Rev 1.2 has not yet been tested, but changes were minimal - no issues are to be expected. Stock situations as well as component rotations at JLC may change over time and hence I can not guarantee for the BOM/CPL files to work…

E80-1800-pcb universal: common questions

What microcontroller does the E80-1800-pcb universal use?

The E80-1800-pcb universal is built around the STM32F072RBTX, from the STM32 family.

How big is the E80-1800-pcb universal?

The E80-1800-pcb universal measures 382 × 160 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the E80-1800-pcb universal?

200 components, from 21 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the E80-1800-pcb universal design files?

From the ebastler/E80-1800 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the E80-1800-pcb universal design in my own project?

Yes, under the terms of its BSD-2-Clause license, which ebastler chose for the repository.

Can I test firmware for the E80-1800-pcb universal without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
