64x64 RGB LED Matrix - 3mm Pitch
4096-pixel RGB LED matrix panel, 64x64 at 3 mm pitch, with dual IDC connectors for chaining. Requires 13 digital pins and a 5V supply; ultra-high-density variant for compact high-resolution video wall applications.
Pinout
- R1
Upper-half red data input for the RGB matrix HUB75-style IDC interface; Adafruit Learn documents R/G/B upper socket signals and notes label variants such as R0/R1 are functionally equivalent.
Type · Signal - G1
Upper-half green data input for the RGB matrix HUB75-style IDC interface.
Type · Signal - B1
Upper-half blue data input for the RGB matrix HUB75-style IDC interface.
Type · Signal - R2
Lower-half red data input for the RGB matrix HUB75-style IDC interface; Adafruit states lower socket R/G/B correspond to R2/G2/B2.
Type · Signal - G2
Lower-half green data input for the RGB matrix HUB75-style IDC interface.
Type · Signal - B2
Lower-half blue data input for the RGB matrix HUB75-style IDC interface.
Type · Signal - A
Row address select input; Adafruit describes address pins A/B/C/D for RGB matrix panels.
Type · Signal - B
Row address select input for the RGB matrix panel.
Type · Signal - C
Row address select input for the RGB matrix panel.
Type · Signal - D
Row address select input for larger RGB matrix panels; Adafruit states address pins A, B, C, D are used by supported panels.
Type · Signal - CLK
Pixel clock/control input; Adafruit documents CLK alongside A/B/C/D/LAT/OE as shared matrix control signals.
Type · Signal - LATSTB
Latch/strobe control input; Adafruit notes LAT may be labelled STB on panels.
Type · Signal - OE
Output-enable control input for the RGB matrix panel.
Type · Signal - 5V
Panel power input; Adafruit states these panels require a good 5V power supply and may need several amps per panel.
Type · PowerVoltage · 5V - GND
Ground return for panel power/control; Adafruit states all ground connections should be connected to GND.
