DehneEVSE-Hardware: common questions

What microcontroller does the DehneEVSE-Hardware use?

The DehneEVSE-Hardware is built around the Arduino Nano 33 IoT, from the AVR/Arduino family.

How big is the DehneEVSE-Hardware PCB?

The DehneEVSE-Hardware measures 188 × 98 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DehneEVSE-Hardware?

46 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the DehneEVSE-Hardware design files?

From the sebdehne/DehneEVSE-Hardware repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the DehneEVSE-Hardware design in my own project?

Yes, under the terms of its GPL-3.0 license, which sebdehne chose for the repository.

Can I test firmware for the DehneEVSE-Hardware 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.
