Hackboard: common questions

What microcontroller does the Hackboard use?

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

How big is the Hackboard PCB?

The Hackboard measures 319.5 × 129 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hackboard?

251 components, from 13 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 Hackboard design files?

From the qwel-exe/hackboard 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 Hackboard design in my own project?

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

Can I test firmware for the Hackboard 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.
