32x32_RGB_LED_Matrix_-_4mm_pitch_SKU_DFR0472-DFRobot

Introduction

This is a 32x32 RGB LED Matrix Panel, it has 1024 full-color RGB LEDs in all. Each LED can be independently addressed and controlled. It requires at least 13 digital GPIOs to control the LED matrix. The led matrix has 2 IDC connectors (DATA_IN, DATA_OUT) on the back, you can cascade multiple panels and make a huge screen together. BUT Arduino doesn’t support this function, its speed is not enough to multiple panel. What's more, it is a high brightness, long life, no pollution, pure color LED display module. It can be used both indoor and outdoor, safety and stability, the module can not be mutually extrusion deformation, also can be used normally in harsh environment.

Note: This panel needs a 5V@3A power supply. And if you connect 2 or more screen, it needs a high performance controller, such as Mega 2560, Raspberry, etc.

Tutorial

According to the pinout to connect, then upload the code to UNO, you will be able to see a beautiful display effect.

Requirements

• Hardware

  • DFRduino UNO R3 x1
  • DFR0471 x1
  • DuPont cables

• Software

  • Arduino IDE Click to Download Arduino IDE from Arduino®

Connection Diagram

Note: It needs an external power supply, the USB is only 5V@500mA, not enough power.
