Pico-HABakuk: common questions

What microcontroller does the Pico-HABakuk use?

The Pico-HABakuk is built around the RP2040, from the RP2040/RP2350 family.

How big is the Pico-HABakuk PCB?

The Pico-HABakuk measures 52 × 51.3 mm, has 2 copper layers and is 1 mm thick.

How many components are on the Pico-HABakuk?

78 components, from 55 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pico-HABakuk design files?

From the serych/pico-HABakuk repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pico-HABakuk design in my own project?

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

Can I test firmware for the Pico-HABakuk 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.
