About the RP2040-Zero-Pico-Debug-Adapter PCB

RP2040-Zero-Pico-Debug-Adapter is an open source RP2040/RP2350 PCB design by starkensan, published on GitHub. It is a 2-layer board measuring 30 × 40 mm, with 8 components from 5 distinct parts.

Its main chip is the RP2040-ZERO, from the RP2040/RP2350 family. By type, the board carries 4 resistors, 3 connectors and 1 IC.

From the project

KiCad 9 project for a small 2-layer adapter PCB that mounts a Waveshare RP2040-Zero module and exposes the debugprobe-zero SWD/UART signals for Raspberry Pi Pico targets.

The RP2040-Zero-Pico-Debug-Adapter is built around the RP2040-ZERO, from the RP2040/RP2350 family.

How big is the RP2040-Zero-Pico-Debug-Adapter PCB?

The RP2040-Zero-Pico-Debug-Adapter measures 30 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RP2040-Zero-Pico-Debug-Adapter?

8 components, from 5 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 RP2040-Zero-Pico-Debug-Adapter design files?

From the starkensan/RP2040-Zero-Pico-Debug-Adapter 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 RP2040-Zero-Pico-Debug-Adapter design in my own project?

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

Can I test firmware for the RP2040-Zero-Pico-Debug-Adapter 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.
