About the Devboard PCB

Devboard is an open source RP2040/RP2350 PCB design by Coder1203, published on GitHub. It is a 2-layer board measuring 21 × 51 mm, with 35 components from 17 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.

Custom Devboard for Hackclub

A small RP2040 devboard I made before trying to build an e-ink reader.

I wanted to create an e-ink reader, but turns out it's pretty hard, so I'll start with a devboard. I just built a Macropad few days ago so I thought how hard can it be. Oh boy, I was wrong.

I was following the blueprint guide, and was overwhelmed, so it took me a lot of time to understand everything. Whenever I didn't know something I googled it. I just wanted a good foundation so that I can build the E-ink reader next on my own.

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?

35 components, from 17 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 Devboard design files?

From the Coder1203/Devboard 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 Devboard design in my own project?

The repository has no license, so all rights stay with Coder1203. 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.
