About the Forti PCB
Forti is an open source STM32 PCB design by calvin-mcd, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 245.7 × 83.8 mm, with 86 components from 15 distinct parts.
Its main chip is the STM32F072C8TX, from the STM32 family. Other key parts include the USBLC6-2SC6, XC6206PXXXMR-REGULATOR_LINEAR and 74AHCT1G125. By type, the board carries 47 diodes, 18 LEDs, 10 capacitors, 4 ICs, 3 resistors and 1 connector.
It belongs with the keyboards designs in this gallery.
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: common questions
What microcontroller does the Forti use?
The Forti is built around the STM32F072C8TX, from the STM32 family.
How big is the Forti PCB?
The Forti measures 245.7 × 83.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Forti?
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 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 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 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.
