Piadcio: common questions

What microcontroller does the Piadcio use?

The Piadcio is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.

How big is the Piadcio PCB?

The Piadcio measures 199.3 × 160 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Piadcio?

39 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Piadcio design files?

From the DouniaBoudefla/piadcio repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Piadcio design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Piadcio without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
