About the Devboard PCB

Devboard is an open source RP2040/RP2350 PCB design by cubit010, published on GitHub. It is a 2-layer board measuring 21 × 51 mm, with 33 components from 15 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the MCP1700x-300xxTT and W25Q128JVS. By type, the board carries 17 capacitors, 7 resistors, 4 connectors, 3 ICs, 1 crystal and 1 switch.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

a devboard i hacked together with minimal sleep

total jlcpcb cost $28.7 (including local taxes and shipping)

similar pinout as raspberry pi pico, but with the gpio 25 broken out, trading a ground pin for a gpio

power pins moved to the top right of the board in a group, both vbus and 3v3

Devboard: common questions

What microcontroller does the Devboard use?

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

How big is the Devboard PCB?

The Devboard measures 21 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Devboard?

33 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Devboard design files?

From the cubit010/devboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Devboard design in my own project?

The repository has no license, so all rights stay with cubit010. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Devboard 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.
