Patch shield digital: common questions

What microcontroller does the Patch shield digital use?

The Patch shield digital is built around the ARDUINO_SHIELD, from the AVR/Arduino family.

How big is the Patch shield digital?

The Patch shield digital measures 197 × 71 mm and is 1.6002 mm thick.

How many components are on the Patch shield digital?

77 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Patch shield digital design files?

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

Can I use the Patch shield digital design in my own project?

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

Can I test firmware for the Patch shield digital 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.
