IO Board V1: common questions
What microcontroller does the IO Board V1 use?
The IO Board V1 is built around the STM32F302C6Tx, from the STM32 family.
How big is the IO Board V1?
The IO Board V1 measures 79 × 49.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the IO Board V1?
88 components, from 45 distinct parts. The full bill of materials is listed on this page.
Where can I download the IO Board V1 design files?
From the AREA-Amiens/AREA.old-boards-hardware repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the IO Board V1 design in my own project?
The repository has no license, so all rights stay with AREA-Amiens. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the IO Board V1 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.
