About the Quaero PCB

Quaero is an open source RP2040/RP2350 PCB design by AethelVeritas, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 312.5 × 136 mm, with 119 components from 9 distinct parts.

Its main chip is the RP2040_Zero, from the RP2040/RP2350 family. By type, the board carries 56 switches, 56 diodes, 3 inductors and 3 resistors.

It belongs with the keyboards and displays & leds designs in this gallery.

Quaero: common questions

What microcontroller does the Quaero use?

The Quaero is built around the RP2040_Zero, from the RP2040/RP2350 family.

How big is the Quaero PCB?

The Quaero measures 312.5 × 136 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Quaero?

119 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Quaero design files?

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

Can I use the Quaero design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which AethelVeritas chose for the repository.

Can I test firmware for the Quaero 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.
