About the Devboarddd PCB

Devboarddd is an open source RP2040/RP2350 PCB design by chendongaoo, published on GitHub under the MIT license. It is a 2-layer board measuring 21 × 51 mm, with 35 components from 16 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the W25Q128JVS and MCP1700X-330XXTT. By type, the board carries 17 capacitors, 8 resistors, 4 connectors, 3 ICs, 2 switches and 1 crystal.

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

From the project

A custom devboard made and designed by myself for the first time!

Probably one of the hardest projects I ever worked on, especially because I had no idea what to expect going in but everything was worthwhile. I learned lots of information from working on this devboard.

Devboarddd: common questions

What microcontroller does the Devboarddd use?

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

How big is the Devboarddd PCB?

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

How many components are on the Devboarddd?

35 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 Devboarddd design files?

From the chendongaoo/Devboarddd 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 Devboarddd design in my own project?

Yes, under the terms of its MIT license, which chendongaoo chose for the repository.

Can I test firmware for the Devboarddd 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.
