About the Devboard PCB

Devboard is an open source RP2040/RP2350 PCB design by emilyahmad, 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 MCP1700X-330XXTT and W25Q16JVZPIQ TR. 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.

From the project

RP2040 MCU, USB-C connector, SPI flash memory, 2 switches, a crystal oscillator & more

A simple devboard with some cute curious george motifs - my first hardware project/PCB, built using @KaiPereira's starter guide on stasis. Like any good devboard, the monkeyboard contains an SoC, memory, power management and I/O interfaces: it receives power via its USB-C connector port, maintains a quad SPI flash memory IC for data storage, 2 multipurpose switches, a crystal oscillator for precise electrical frequencies, and the star of the show, the RP2040 as its MCU.

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 emilyahmad/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 emilyahmad. 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.
