About the RP2040-devboard PCB

RP2040-devboard is an open source RP2040/RP2350 PCB design by Dhruv2212-star, published on GitHub. It is a 4-layer board measuring 44 × 54 mm, with 37 components from 20 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the NCP1117-3.3_TO252 and W25Q128JVS. By type, the board carries 17 capacitors, 9 resistors, 5 connectors, 3 ICs, 1 crystal and 1 switch.

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

Now let me explain to you how i built this devboard :) for a Devboard to work you need to have the basic idea of the chip architecture, with our RP2040 chip, it uses 3.3v for the main power pins but uses 1.1v for the logic pins and fortunately for our chip it has a built in volta

Now let me explain to you how i built this devboard :) for a Devboard to work you need to have the basic idea of the chip architecture, with our RP2040 chip, it uses 3.3v for the main power pins but uses 1.1v for the logic pins and fortunately for our chip it has a built in voltage control which reduces the voltage to 1.1v so no need of extra components

decoupling capacitors- we are using 100nF capacitors per each power pin (IOVDD) and 1uF capacitors for VREGIN and VREGOUT each and 2 100nF capacitors for DVDD pin, 100nF capacitor for ADC_AVDD and 100nF for USB VDD

The KiCad project lives in the Dhruv2212-star/RP2040-devboard repository on GitHub; these links point at the commit this page was built from.

RP2040-devboard: common questions

What microcontroller does the RP2040-devboard use?

The RP2040-devboard is built around the RP2040, from the RP2040/RP2350 family.

How big is the RP2040-devboard PCB?

The RP2040-devboard measures 44 × 54 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RP2040-devboard?

37 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the RP2040-devboard design files?

From the Dhruv2212-star/RP2040-devboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RP2040-devboard design in my own project?

The repository has no license, so all rights stay with Dhruv2212-star. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the RP2040-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.
