ARES FC: common questions
What microcontroller does the ARES FC use?
The ARES FC is built around the STM32F401CCU6, from the STM32 family.
How big is the ARES FC PCB?
The ARES FC measures 57.2 × 57.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ARES FC?
62 components, from 33 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 ARES FC design files?
From the explosion33/ARES 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 ARES FC design in my own project?
Yes, under the terms of its MIT license, which explosion33 chose for the repository.
Can I test firmware for the ARES FC 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.
