GDI-STM: common questions
What microcontroller does the GDI-STM use?
The GDI-STM is built around the STM32G474M_B-C-E_TX, from the STM32 family.
How big is the GDI-STM PCB?
The GDI-STM measures 154 × 160 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the GDI-STM?
304 components, from 58 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 GDI-STM design files?
From the rusefi/rusefi-hardware 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 GDI-STM design in my own project?
The repository has no license, so all rights stay with rusefi. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the GDI-STM 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.
