NeoPixel FlexMatrix 8x32 - 256 x WS2812B RGB LED

This NeoPixel matrix carries 256 RGB LEDs (4.9 × 4.9 mm) with integrated WS2812B driver on a flexible board, arranged as 8 × 32. Several matrices can be connected in series. Each LED is controlled individually via a single output of a microcontroller such as Arduino UNO, Mega, Nano, ESP32 or ESP8266. At full brightness the matrix needs up to 15.36 A, so it belongs on its own, sufficiently strong 5 V power supply.

Recommended Accessories:

• 5V 20A AC/DC 100W Switching Power Supply S-100-5
• Electrolytic Capacitor 3300 µF 6.3 V
• 4-Channel 5V / 3.3V Logic Level Converter
• 3pin JST SM 22AWG Connection Cable 30cm

Features:

• Connection cables with 3-pin plug at input and output, plus a power lead with open ends
• Each LED individually controllable via one data line
• Several modules can be connected in series (data output to data input)
• Library: FastLED or Adafruit NeoPixel, for ESP8266 also WS2812FX and NeoPixelBus
• 300 to 500 Ω resistor in the data line recommended
• With 3.3 V boards such as ESP8266 or ESP32, a level shifter is needed on the data line
• 3300 µF capacitor between GND and 5 V recommended for a stable supply and a long LED life

Application Examples:

• Scrolling text and displays for text, characters and symbols
• Pixel clock like the AWTRIX project
• Lighting on curved surfaces
