Exo pcbs: common questions

What microcontroller does the Exo pcbs use?

The Exo pcbs is built around the STM32G474RBT6, from the STM32 family.

How big is the Exo pcbs PCB?

The Exo pcbs measures 75 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Exo pcbs?

37 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Exo pcbs design files?

From the Exocet-Polytechnique/exo-pcbs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Exo pcbs design in my own project?

Yes, under the terms of its GPL-3.0 license, which Exocet-Polytechnique chose for the repository.

Can I test firmware for the Exo pcbs 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.
