VESX: common questions
What microcontroller does the VESX use?
The VESX is built around the STM32F405RGTX, from the STM32 family.
How big is the VESX PCB?
The VESX measures 100 × 40 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the VESX?
177 components, from 81 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 VESX design files?
From the NormalHuman-Anything/VESX 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 VESX design in my own project?
Yes, under the terms of its CERN-OHL-W-2.0 license, which NormalHuman-Anything chose for the repository.
Can I test firmware for the VESX 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.
