Stm32gbcart: common questions

What microcontroller does the Stm32gbcart use?

The Stm32gbcart is built around the STM32F405RGTx, from the STM32 family.

How big is the Stm32gbcart PCB?

The Stm32gbcart measures 51.4 × 61 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stm32gbcart?

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

Where can I download the Stm32gbcart design files?

From the Emeryth/stm32gbcart repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Stm32gbcart design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which Emeryth chose for the repository.

Can I test firmware for the Stm32gbcart 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.
