About the Beagle PCB

Beagle is an open source RP2040/RP2350 PCB design by euvalennn, published on GitHub. It is a 2-layer board measuring 328.6 × 124.2 mm, with 235 components from 11 distinct parts.

Its main chip is the RaspberryPi_Pico, from the RP2040/RP2350 family. By type, the board carries 155 diodes, 78 switches, 1 module and 1 connector.

It belongs with the keyboards and displays & leds designs in this gallery.

From the project

my first keyboard!

It's been almost a month since I started working on this! I wanted to try making a keyboard myself, but soon realized it's easier said than done 😭\ Overall I'm really happy with how it turned out, I have to admit it took me a pretty long time to finish but I wanted to make sure it was polished and I think I've achieved that :)

The layout resembles that of my MacBook's keyboard (since that's what I mostly use) and I also included a rotary encoder (intended for volume but can be customized) and an OLED screen to show animations, graphics, or anything else you may want to put there. There's an…

Beagle: common questions

What microcontroller does the Beagle use?

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

How big is the Beagle PCB?

The Beagle measures 328.6 × 124.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Beagle?

235 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Beagle design files?

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

Can I use the Beagle design in my own project?

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

Can I test firmware for the Beagle 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.
