LED Display MAX7219 Module having 8 Bit Digital Segment tube with 7 display Segments for Arduino MCU/51/AVR/STM32

Description

• APPLICATION: LED Matrix Displays; Panel Meters; Industrial Controllers;7-Segment Displays; Bar-Graph displays
• Material: PCB + Electronic Components
• MAX7219 is an integrated serial input / output common-cathode display driver, which connects your microprocessor to a 7-segment digital LED display with 8 digits
• it is compatible of 5V / 3.3V microcontroller; Only three IO ports are used to drive the eight digit display
• Note: VCC and GND do not reversed, it would burn the chip; 51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines.
