OpenHardwareExG Shield: common questions

What microcontroller does the OpenHardwareExG Shield use?

The OpenHardwareExG Shield is built around the ARDUINO_SHIELD, from the AVR/Arduino family.

How big is the OpenHardwareExG Shield?

The OpenHardwareExG Shield measures 125.1 × 59.7 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the OpenHardwareExG Shield?

195 components, from 34 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 OpenHardwareExG Shield design files?

From the OpenElectronicsLab/OpenHardwareExG_Shield repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the OpenHardwareExG Shield design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which OpenElectronicsLab chose for the repository.

Can I test firmware for the OpenHardwareExG Shield 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.
