Qezberry: common questions

What microcontroller does the Qezberry use?

The Qezberry is built around the RP2040, from the RP2040/RP2350 family.

How big is the Qezberry PCB?

The Qezberry measures 194.3 × 79 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Qezberry?

111 components, from 34 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 Qezberry design files?

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

Can I use the Qezberry design in my own project?

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

Can I test firmware for the Qezberry without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
