USB-PiDU: common questions

What microcontroller does the USB-PiDU use?

The USB-PiDU is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the USB-PiDU PCB?

The USB-PiDU measures 71.5 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the USB-PiDU?

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

Where can I download the USB-PiDU design files?

From the PhirePhly/USB-PiDU repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the USB-PiDU design in my own project?

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

Can I test firmware for the USB-PiDU 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.
