MicroRusEFI: common questions
What microcontroller does the MicroRusEFI use?
The MicroRusEFI is built around the STM32F427VGT6, from the STM32 family.
How big is the MicroRusEFI PCB?
The MicroRusEFI measures 80.6 × 93.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MicroRusEFI?
235 components, from 75 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 MicroRusEFI 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 MicroRusEFI 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 MicroRusEFI 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.
