Keyboard-V2: common questions
What microcontroller does the Keyboard-V2 use?
The Keyboard-V2 is built around the STM32F723IEK6, from the STM32 family.
How big is the Keyboard-V2 PCB?
The Keyboard-V2 measures 317.8 × 142 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Keyboard-V2?
230 components, from 111 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 Keyboard-V2 design files?
From the nKumar2015/Keyboard-V2 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 Keyboard-V2 design in my own project?
The repository has no license, so all rights stay with nKumar2015. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Keyboard-V2 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.
