From the project
13u pcb for Førti
The F�rti pcb (40 in Norwegian) is a 13u 40% pcb with full basekit support for the upcoming F�rti keyboard case created and designed by xonuss and xezioh that is based on Geon's F1-8x. The pcb takes its layout and design cues from the oxymoron, bully and ttocyobitna amongst others. It's a stm32 based pcb for low cost, good performance.

Forti rev 2: common questions
What microcontroller does the Forti rev 2 use?
The Forti rev 2 is built around the STM32F072C8TX, from the STM32 family.
How big is the Forti rev 2 PCB?
The Forti rev 2 measures 245.7 × 82.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Forti rev 2?
86 components, from 15 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 Forti rev 2 design files?
From the calvin-mcd/Forti 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 Forti rev 2 design in my own project?
It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Forti rev 2 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.
