Feature

●The MAX7219 is an integrated serial input/output common cathode display driver
●The MAX7219 is connected to a microprocessor and an 8-digit 7-segment digital LED display. It can also be connected to a bar graph display or 64 independent LEDs
●This module includes an on-chip B-type BCD encoder, multi-channel scan loop, segment word driver, and 8 x 8 static RAM for storing each data
●The entire device includes 150μA low power shutdown mode, analog and digital brightness control, and a scan limit register that allows the user to display 1/8-bit data, and detection mode to emit all LEDs
●Each data can be addressed. No need to rewrite all displays when updating. The MAX7219 also allows the user to choose whether to encode each data
