PQDB-Hardware: common questions

What microcontroller does the PQDB-Hardware use?

The PQDB-Hardware is built around the ARDUINO_SHIELD, from the AVR/Arduino family.

How big is the PQDB-Hardware PCB?

The PQDB-Hardware measures 147.3 × 146.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PQDB-Hardware?

73 components, from 20 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 PQDB-Hardware design files?

From the augustocrmattos/PQDB-Hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the PQDB-Hardware design in my own project?

The repository has no license, so all rights stay with augustocrmattos. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PQDB-Hardware 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.
