GranulArduino: common questions

What microcontroller does the GranulArduino use?

The GranulArduino is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How many components are on the GranulArduino?

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

Where can I download the GranulArduino design files?

From the benjiaomodular/GranulArduino repository on GitHub, which has a netlist; the links under Design files point to each one.

Can I use the GranulArduino design in my own project?

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

Can I test firmware for the GranulArduino 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.
