About the Devboard PCB

Devboard is an open source Raspberry Pi PCB design by LeoMos10, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 29.7 × 51 mm, with 45 components from 25 distinct parts.

Its main chip is the RP2354B, from the Raspberry Pi family. Other key parts include the MCP1700T-3302E/TT. By type, the board carries 17 capacitors, 11 resistors, 6 connectors, 4 switches, 3 diodes and 2 ICs.

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

idk a devboard

Devboard is a custom Raspberry Pi RP2354B development board based on the Hack Club devboard guide. The schematic and PCB are being designed in KiCad.

I wanted to design a microcontroller board itself, with USB-C, GPIO, onboard buttons and status LEDs.

- Raspberry Pi RP2354B microcontroller - USB-C connector - 3.3 V power supply with an inductor and a Schottky diode - Yellow LED and a RGB LED - BOOTSEL, RUN and 2 user buttons - 2.54 mm pin headers, plus additional headers, SWD debug probe

Devboard: common questions

What microcontroller does the Devboard use?

The Devboard is built around the RP2354B, from the Raspberry Pi family.

How big is the Devboard PCB?

The Devboard measures 29.7 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Devboard?

45 components, from 25 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 LeoMos10/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?

Yes, under the terms of its GPL-2.0 license, which LeoMos10 chose for the repository.

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 Raspberry Pi firmware against it before you order a PCB.
