About the QD-Main board

QD-Main board is an open source RP2040/RP2350 PCB design by Cheesylorry, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 93.1 × 49.5 mm, with 33 components from 22 distinct parts.

Its main chip is the RaspberryPi_Pico, from the RP2040/RP2350 family. Other key parts include the TPS563209DDCR and TPS561201DDCR. By type, the board carries 4 resistors, 2 ICs, 2 connectors, 2 inductors, 1 module and 1 fuse.

From the project

A Repository for the Quantum Demonstrator Lite, a Plug and play Quantum Algorythm for Students. Integrates into SpinDrops, a software for simmulating up to three Qubits.

Parts needed for the PCB can be found via the Schematics, the BOM or here.

QD-Main board: common questions

What microcontroller does the QD-Main board use?

The QD-Main board is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the QD-Main board?

The QD-Main board measures 93.1 × 49.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the QD-Main board?

33 components, from 22 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 QD-Main board design files?

From the Cheesylorry/Quantum-Demonstrator-Lite 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 QD-Main board design in my own project?

Yes, under the terms of its GPL-2.0 license, which Cheesylorry chose for the repository.

Can I test firmware for the QD-Main board 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.
