About the RP2040 PCB

RP2040 is an open source RP2040/RP2350 PCB design by Hung-Chi970104, published on GitHub. It is a 2-layer board measuring 21 × 51 mm, with 51 components from 26 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the RT6154AGQW and W25Q64JVXGIQ. By type, the board carries 18 capacitors, 18 resistors, 4 connectors, 3 ICs, 3 diodes and 2 switches.

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

From the project

Custom RP2040 development board with USB-C, buck-boost regulation, external-power support, and exposed GPIO.

- Upgraded flash storage from 2MB (W25Q16JVUXIQ TR) to 16MB (W25Q64JVXGIQ) - Replaced MCP1700x-330xxTT (linear regulator) with RT6154AGQW (buck-boost switching regulator) - Added Schottky Diode to allow external power supply - Added a RESET button - Changed 33pF crystal cap to 15pF to match the crystal I ordered

- 2 layers - Single-sided component placement - 2.6mm board thickness - HASL (with lead) surface finish - 1oz outer copper weight

The KiCad project lives in the Hung-Chi970104/RP2040 repository on GitHub; these links point at the commit this page was built from.

RP2040: common questions

What microcontroller does the RP2040 use?

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

How big is the RP2040 PCB?

The RP2040 measures 21 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RP2040?

51 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the RP2040 design files?

From the Hung-Chi970104/RP2040 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 design in my own project?

The repository has no license, so all rights stay with Hung-Chi970104. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the RP2040 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.
