About the RP2354-Micro-Devboard PCB

RP2354-Micro-Devboard is an open source RP2040/RP2350 PCB design by 0x62b, published on GitHub. It is a 2-layer board measuring 19.5 × 22.6 mm, with 32 components from 14 distinct parts.

Its main chip is the RP2350_60QFN, from the RP2040/RP2350 family. Other key parts include the MCP1700x-330xxTT. By type, the board carries 17 capacitors, 6 resistors, 3 connectors, 2 ICs, 2 switches and 1 crystal.

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

From the project

A small RP2354 based devboard

This is probably just going to be used for some small boards that need an RP2350 but that I don't want to directly build the MCU into, without having to go acquire a Xiao, supermini, or something like that.

*many of the files are named as RP2350 because that is what I was using before

The board is compatible with any firmware written for the Pi Pico/RP2350, as long as they don't use the omitted GPIO pins anyway...

RP2354-Micro-Devboard: common questions

What microcontroller does the RP2354-Micro-Devboard use?

The RP2354-Micro-Devboard is built around the RP2350_60QFN, from the RP2040/RP2350 family.

How big is the RP2354-Micro-Devboard PCB?

The RP2354-Micro-Devboard measures 19.5 × 22.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RP2354-Micro-Devboard?

32 components, from 14 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 RP2354-Micro-Devboard design files?

From the 0x62b/RP2354-Micro-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 RP2354-Micro-Devboard design in my own project?

The repository has no license, so all rights stay with 0x62b. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the RP2354-Micro-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.
