Description
Note: The LED strips and power supply are not included with this product — they are purchased separately.
The Koshi Electronics SPI to DC Decoder converts the SPI signal from your pixel controller into a normal DC output — so you can run ordinary (non-addressable) single-colour or RGB/RGBW strips directly from your pixel controller. No separate controller needed.
Key Features
- Universal SPI Input: works with all standard pixel ICs — WS2811, WS2812, 1903.
- Two Versions: Single Channel — single-colour strip or relay switch; Four Channel — RGB / RGBW strips.
- 3A Per Channel Output: clean PWM DC for smooth dimming and colour mixing.
- Wide Voltage: runs on a 5–24V DC supply.
- Compact Inline Design: fits easily between the controller and the strip.
Single vs Four Channel
| Feature | Single Channel | Four Channel |
|---|---|---|
| Outputs | 1 | 4 |
| Best For | Single-colour strip or relay trigger | RGB / RGBW strips |
| Use Case | Automating one colour section | Full colour mixing, pixel-fed |
Perfect For
- Mixing normal strips into a pixel setup
- Sign board and accent lighting
- Switching a relay or load from a pixel controller
- Combining single-colour and addressable together
Complete Your Setup
- Pixel LED Controllers (W1000-PRO, SP107E, SP621E…) → — to feed the SPI signal

How To Set Up (Wiring)
- Connect the pixel controller's SPI data + GND to the decoder's input.
- Connect the decoder's DC output to your single-colour or RGB/RGBW strip.
- Power the decoder and strip from a 5–24V SMPS.
