{"title":"32x32 RGB LED Matrix Panel - 4mm Pitch","handle":"32x32-rgb-led-matrix-panel-4mm-pitch","url":"/products/32x32-rgb-led-matrix-panel-4mm-pitch","description":"A 32×32 full-colour RGB LED matrix panel with 1024 LEDs at 4mm pitch, measuring approximately 5 inches (128mm) square. These panels are commonly used in video walls and signage, delivering bright, vivid colours with good white balance uniformity. On the back, dual IDC connectors (input and output) allow panels to be chained for larger displays.\n\nThe panel uses a 1:16 scan rate with 12 × 16-bit latches. It requires 13 digital pins (6 data + 7 control) and continuous redrawing to achieve PWM colour — on a 16 MHz Arduino, 12-bit colour (4096 colours) is achievable at ~40% CPU usage. Higher-performance controllers (FPGA, Raspberry Pi, Propeller) can drive these panels to their full potential.\n\nKey Features\n\n\n1024 RGB LEDs – 32×32 pixel resolution at 4mm pitch\n\n12-Bit Colour on Arduino – 4096 colours with example library code\n\nChainable – Dual IDC input/output connectors\n\nPre-White Balanced – Good colour uniformity across the panel\n\nCompact – ~128 × 128mm (5 × 5 inches)\n\n\nSpecifications\n\n\nResolution – 32 × 32 pixels (1024 total)\n\nPixel Pitch – 4mm\n\nScan Rate – 1:16\n\nOperating Voltage – 5V DC\n\nCurrent Draw – Up to 4A per panel\n\nDigital Pins Required – 13 (6 data + 7 control)\n\nRAM Required (Arduino) – ~1600 bytes for 12-bit colour buffer\n\n\nIdeal For\n\nLED video walls and signage projects\nArduino, Raspberry Pi, and FPGA display projects\nAnimations, graphics, and text displays\n\n\nPackage Contents\n\n1× 32×32 RGB LED Matrix Panel\n2× IDC cables\n1× Power cable\n4× Mounting screws with mini-magnets\n\n\n\nNote: Requires a 5V 4A power supply (not included).
