Qpcb: common questions
What microcontroller does the Qpcb use?
The Qpcb is built around the Pico, from the RP2040/RP2350 family.
How big is the Qpcb PCB?
The Qpcb measures 280 × 205 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Qpcb?
226 components, from 80 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 Qpcb design files?
From the leonardobove/qpcb 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 Qpcb design in my own project?
The repository has no license, so all rights stay with leonardobove. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Qpcb 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.
