MAX7219 8×8 LED Matrix Display

₹110.00

Overview

The MAX7219 8×8 LED Matrix Display Module is a compact, versatile display solution integrating 64 individual red light-emitting diodes arranged in an 8-row by 8-column grid. Driven by the integrated MAX7219 driver IC, this module offloads matrix scanning, multiplexing, and brightness control from the main host microcontroller, allowing seamless display drive using just 3 SPI control lines (VCC, GND, DIN, CS, CLK).

The board includes input (IN) and output (OUT) header connections, enabling multiple modules to be cascaded together in series to form larger LED banner displays, digital clocks, or moving message displays.
