What it is
The WS2812B 5x5 RGB LED Matrix Module for Arduino, Raspberry Pi & ESP32 is a compact 25-pixel addressable display built around the popular WS2812B driver architecture. It uses a single-wire data signal instead of I2C, SPI, or UART, making it useful for animations, icons, numeric readouts, badges, mini dashboards, and other microcontroller projects; check the module pinout and WS2812B datasheet details before wiring.
Pins
Refer to the silkscreen labels on the board/module and the listing photos for exact pin names. WS2812B matrices are typically wired with power, ground, and a data path, but confirm the actual input and output markings on your revision before connecting it to Arduino, Raspberry Pi, or ESP32 hardware.

Frequently Asked Questions
How do I connect the WS2812B 5x5 RGB LED Matrix to an Arduino or ESP32?
Use the module's labeled power, ground, and data connections, and verify the exact pinout on the board silkscreen or listing photos before wiring. The matrix uses a single-wire WS2812B data signal, so software examples for WS2812B or NeoPixel-style LEDs are the right starting point.
Can this WS2812B LED matrix work with Raspberry Pi?
Yes, the product description lists Raspberry Pi as a supported platform. Confirm the module pinout and use software or libraries intended for WS2812B addressable LEDs.
How many LEDs are on this 5x5 RGB LED matrix module?
This module combines 25 individually controllable RGB LEDs in a 5 x 5 layout. That makes it suitable for small animations, icons, status indicators, and compact display effects.
Can I chain multiple WS2812B 5x5 matrices together?
Yes, the description states that each pixel can be chained over a single-wire data signal. This makes it practical to build larger addressable LED arrays without complex wiring.
Is the WS2812B 5x5 RGB LED Matrix an I2C or SPI display?
No. Unlike I2C, SPI, or UART modules, this matrix uses the WS2812B single-wire addressable LED protocol.
