About the Openrb pico hw PCB

Openrb pico hw is an open source RP2040/RP2350 PCB design by hazptr, published on GitHub. It is a board, with 31 components from 16 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the RT9080-33 and W25Q16JV. By type, the board carries 14 capacitors, 8 resistors, 3 ICs, 2 LEDs, 1 crystal and 1 fuse.

From the project

KiCad hardware design for the OpenRB rev 0.2 RP2040 rhythm-game adapter board (runs the openrb-pico firmware).

Editable KiCad source rebuilt from the recovered artifacts (the original EasyEDA project was lost). See ../RECONSTRUCTION.md for the verified netlist this was built from.

To regenerate: python3 gensch.py && kicad-cli sch upgrade openrb/openrb.kicadsch

Openrb pico hw: common questions

What microcontroller does the Openrb pico hw use?

The Openrb pico hw is built around the RP2040, from the RP2040/RP2350 family.

How many components are on the Openrb pico hw?

31 components, from 16 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 Openrb pico hw design files?

From the hazptr/openrb-pico-hw repository on GitHub, which has the schematic, a netlist and the BOM; the links under Design files point to each one.

Can I use the Openrb pico hw design in my own project?

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

Can I test firmware for the Openrb pico hw 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.
