From the project

An I2c/CAN Module designed for the Shell Eco Marathon

A simple modular PCB for CAN, I2c and headlights connectors. This controller was designed in order to simplify the electrical systems that partake in our Urban Vehicle.

By integrating CAN and I2C communication protocols, this board enables seamless interaction between various electronic modules while reducing wiring complexity. The dedicated headlight connectors allow for easy control of lighting systems.

EcoCAN: common questions

What microcontroller does the EcoCAN use?

The EcoCAN is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the EcoCAN PCB?

The EcoCAN measures 66 × 62.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the EcoCAN?

13 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the EcoCAN design files?

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

Can I use the EcoCAN design in my own project?

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

Can I test firmware for the EcoCAN 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.
