Electronics Control Unit (ECU): common questions
What microcontroller does the Electronics Control Unit (ECU) use?
The Electronics Control Unit (ECU) is built around the C2040, from the RP2040/RP2350 family.
How big is the Electronics Control Unit (ECU) PCB?
The Electronics Control Unit (ECU) measures 120 × 100 mm, has 8 copper layers and is 1.699 mm thick.
How many components are on the Electronics Control Unit (ECU)?
344 components, from 86 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 Electronics Control Unit (ECU) design files?
From the synthesissolutions/geeksforkids 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 Electronics Control Unit (ECU) design in my own project?
The repository has no license, so all rights stay with synthesissolutions. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Electronics Control Unit (ECU) without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
