Camper van: common questions

What microcontroller does the Camper van use?

The Camper van is built around the ARDUINO_NANO_ESP32, from the AVR/Arduino family.

How big is the Camper van PCB?

The Camper van has 2 copper layers and is 1.6 mm thick.

How many components are on the Camper van?

253 components, from 153 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 Camper van design files?

From the akladnig/CamperVan 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 Camper van design in my own project?

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

Can I test firmware for the Camper van 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.
