About the Devboard PCB

Devboard is an open source RP2040/RP2350 PCB design by LawrnardKerman, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 20.5 × 52.8 mm, with 85 components from 32 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the W25Q128JVE, TPS63031DSK and MCP73831-2-OT. By type, the board carries 40 connectors, 18 resistors, 14 capacitors, 5 diodes, 4 ICs and 1 transistor.

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

From the project

there's 16MB of flash memory by default, you can just change it in the bom, the prod files are for jlcpcb pcb assembly it should work as a raspberry pi pico because most of the components are the same there's a 3.3v in and gnd connector next to the battery connector you can just

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 20.5 × 52.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Devboard?

85 components, from 32 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 LawrnardKerman/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-3.0 license, which LawrnardKerman 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 RP2040/RP2350 firmware against it before you order a PCB.
