Gesc: common questions

What microcontroller does the Gesc use?

The Gesc is built around the STM32F405RGTx, from the STM32 family.

How big is the Gesc PCB?

The Gesc measures 111 × 111 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Gesc?

150 components, from 48 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gesc design files?

From the CTSchorsch/gesc repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Gesc design in my own project?

The repository has no license, so all rights stay with CTSchorsch. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Gesc 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.
