GN10Mainboard: common questions

What microcontroller does the GN10Mainboard use?

The GN10Mainboard is built around the STM32G474RETx, from the STM32 family.

How big is the GN10Mainboard PCB?

The GN10Mainboard measures 80 × 60 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the GN10Mainboard?

124 components, from 56 distinct parts. The full bill of materials is listed on this page.

Where can I download the GN10Mainboard design files?

From the ararobo/GN10Mainboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the GN10Mainboard design in my own project?

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

Can I test firmware for the GN10Mainboard 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.
