Available Options


This is the standard 8x32 LED Matrix for digital signs.


  • The MAX7219 is compact with serial input/output common-cathode display drivers that interface microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs.
  • Included on-chip are a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM that stores each digit.
  • Only one external resistor is required to set the segment current for all LEDs. A convenient 3-wire serial interface connects to all common µPs. Individual digits may be addressed and updated without rewriting the entire display.
  • The MAX7219 also allow the user to select code B decoding or no-decode for each digit.
  • The devices include a 150µA low-power shutdown mode, analog and digital brightness control, a scan limit register that allows the user to display from 1 to 8 digits, and a test mode that forces all LEDs on.
