About the MsDb-1A3 PCB

MsDb-1A3 is an open source RP2040/RP2350 PCB design by camaradadasausturias-art, published on GitHub. It is a 2-layer board measuring 21.8 × 52.5 mm, with 33 components from 18 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the NCP1117-3.3_SOT223 and W25Q128JVS. By type, the board carries 17 capacitors, 7 resistors, 3 ICs, 3 connectors and 1 switch.

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

From the project

Simple dev board inspired by the raspberry Pi Pico

Hey there, fellow human! I'm a portuguese 17 year old highschooler with aspirations of getting into aerospacial engineering one day. And since I know how important it is to start building experience early, I decided to try out a hackclub starter project. And what an undertaking this was. I picked the "Design a custom PCB" thinking it couldnt be THAT hard. Yeah no, hard would be the understatement of the century. I had hardly ever touched a CAD program in my life, and KiCAD looked like it'd have a very sharp looking skill curve. As it did indeed. But I presevered. Despite me relentlessly…

MsDb-1A3: common questions

What microcontroller does the MsDb-1A3 use?

The MsDb-1A3 is built around the RP2040, from the RP2040/RP2350 family.

How big is the MsDb-1A3 PCB?

The MsDb-1A3 measures 21.8 × 52.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MsDb-1A3?

33 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the MsDb-1A3 design files?

From the camaradadasausturias-art/MsDb-1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MsDb-1A3 design in my own project?

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

Can I test firmware for the MsDb-1A3 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.
