RGB LED Matrix Panel 64×32 Pixels 3.0mm Pitchs





RGB Full-Color LED Matrix Panel, 64×32 Pixels, Adjustable Brightness



  • 2048 individual RGB LEDs, full-color display, adjustable brightness.
  • 64 x 32 pixels, 3mm pitch, allows displaying text, colorful images, or animation.
  • 192 x 96mm dimensions, moderate size, suitable for DIY desktop display or wall mount display.
  • Onboard two HUB75 headers, one for controller data input, one for output, and chain support.
  • Provides open-source development resources and tutorials, for use with Raspberry Pi, Pico, ESP32, Arduino, and so on.


DIMENSIONS 192mm × 96mm
PIXELS 64 × 32=2048 DOTS
CONTROL TYPE synchronization
DRIVING 1/16 scan
POWER SUPPLY 5V / 2.5A(VH4 header input)

Header Definition


VCC 5V power input GND Ground
R1 R higher bit data R2 R lower bit data
G1 G higher bit data G2 G lower bit data
B1 B higher bit data B2 B lower bit data
A A line selection B B line selection
C C line selection D D line selection
