ECU STM V1: common questions

What microcontroller does the ECU STM V1 use?

The ECU STM V1 is built around the ATMEGA2560-A_perso, from the AVR/Arduino family.

How big is the ECU STM V1 PCB?

The ECU STM V1 measures 93 × 108 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ECU STM V1?

201 components, from 43 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 ECU STM V1 design files?

From the mstevanin4/ECU_STM_V1 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the ECU STM V1 design in my own project?

The repository has no license, so all rights stay with mstevanin4. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ECU STM V1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
