Chademo hardware: common questions

What microcontroller does the Chademo hardware use?

The Chademo hardware is built around the ATSAM3X8EA-AU, from the Microchip SAM family.

How big is the Chademo hardware PCB?

The Chademo hardware measures 100 × 107.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Chademo hardware?

129 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 Chademo hardware design files?

From the larsrengersen/chademo-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 Chademo hardware design in my own project?

Yes, under the terms of its MIT license, which larsrengersen chose for the repository.

Can I test firmware for the Chademo hardware without the hardware?

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