MAX7219 MAX 7219 LED Dot Matrix 8x8 8 x 8 Module DIY Kit MCU

Deskripsi : The MAX7219 is an integrated serial input / output common cathode display driver . It connects a microprocessor to an 8 -digit 7- segment digital LED display. It can also be connected to a bar graph display or 64 independent LEDs . It includes an on-chip B -type BCD encoder, multiple scanning loops, segment word drivers, and an 8 * 8 static RAM to store every data. There is only one external register to set the segment current of each LED . A convenient four-wire serial interface can be connected to all general-purpose microprocessors. Each data can be addressed without updat MAX7219 dot matrix module LH control LED Display for Arduino The MAX7219 is an integrated serial input / output co-cathode display driver that connects a microprocessor with an 8-digit 7-segment digital LED display or a bar graph display or 64 independent LEDs. Which includes an on-chip B-type BCD encoder, multi-scan circuit, segment word drive, but also a 8 * 8 static RAM used to store each data. Only one external register is used to set the segment current for each LED. A convenient four-wire serial interface can be connected to all common microprocessors. Each data can be addressed at the time of updating without having to rewrite all the displays. The MAX7219 also allows the user to select or not code for each data. The entire device contains a 150μA low power shutdown mode, analog and digital brightness control, a scan limit register allows the user to display 1-8 bits of data, and a test mode for all LEDs to emit light. Only need 3 IO port can drive a dot matrix! Dot matrix display without flicker! Support cascade! Specification: 1. A single module can drive an 8 * 8 2. Module operating voltage: 5V 3.
