RP2040-Zero Case for SignalRGB LED Strip Controller

A compact case for the Waveshare RP2040-Zero, built as a USB controller for addressable LED strips in SignalRGB. Plug it into your PC over USB-C, connect the strip and control it from SignalRGB like any other RGB device.

What you need:

• Waveshare RP2040-Zero

• 3-pin LED strip connector (e.g. JST SM 3-pin)

• A few short wires

• Addressable 5v LED strip

Features:

• Snug fit for the Waveshare RP2040-Zero

• Opening for the USB-C port

• Sliding lid, no screws or glue needed

• Built-in slot that holds a male JST SM 2.54 mm 3-pin LED strip connector (5V / DATA / GND), so the strip plugs in and out without touching the board(use cover only cables .stl if you solder led strip directly to board)

• Room inside for short wires soldered straight to the pads

Firmware & SignalRGB plugin:

• The firmware and the SignalRGB plugin are open source (MIT) on GitHub: https://github.com/osait98/rp2040-zero-signalrgb/releases

• Download the zip from the latest release. It contains:
  - "rp2040-zero-signalrgb.uf2" – prebuilt firmware
  - “RP2040_Zero_LED_Strip.js” – SignalRGB plugin

Installation:

1. Hold BOOT button on board while plugging in the board to computer and copy the ".uf2" file to the RPI-RP2 drive.

2. Copy the ".js" file to “Documents\WhirlwindFX\Plugins” and restart SignalRGB.

3. In Devices > RP2040-Zero LED Strip, add a component with your LED count. You never need to reflash, because the LED count is set in SignalRGB.

Wiring:

| LED strip | RP2040-Zero |
| DIN (data) | GPIO29 |
| GND | GND |
| +5V | 5V |

Supports up to 600 LEDs. For long strips, power them from a separate 5 V supply rather than through USB.
