About the Devboard-RGB-LED-custom button I2C header PCB

Devboard-RGB-LED-custom button I2C header is an open source RP2040/RP2350 PCB design by norayr-noro, published on GitHub. It is a 2-layer board measuring 39 × 60 mm, with 42 components from 20 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the NCP1117-3.3_SOT223 and W25Q128JVS. By type, the board carries 17 capacitors, 12 resistors, 5 connectors, 3 ICs, 2 switches and 2 diodes.

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

From the project

I am building a custom RP2040-based development board based on the Hack Club devboard guide, with added features including an RGB LED, a user input button, and an I2C header, along with a custom PCB design for improved usability and appearance.

And in the end, you will be able to build something like this (final PCB design):

Devboard-RGB-LED-custom button I2C header: common questions

What microcontroller does the Devboard-RGB-LED-custom button I2C header use?

The Devboard-RGB-LED-custom button I2C header is built around the RP2040, from the RP2040/RP2350 family.

How big is the Devboard-RGB-LED-custom button I2C header PCB?

The Devboard-RGB-LED-custom button I2C header measures 39 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Devboard-RGB-LED-custom button I2C header?

42 components, from 20 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-RGB-LED-custom button I2C header design files?

From the norayr-noro/Devboard-RGB-LED-custom_button_I2C_header 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-RGB-LED-custom button I2C header design in my own project?

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

Can I test firmware for the Devboard-RGB-LED-custom button I2C header 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.
