5 PCS 8 Digit 7 Segment Module MAX7219 8 Bit Digital Segment Tube LED Display Module Compatible with Arduino MCU/51/AVR/STM32/Raspberry Pi 4 Model B
Description:1: MAX7219 is an integrated serial input / output common-cathode display drivers, which connects the microprocessor 7-segment digital LED display with 8 digits, you can also connect a bar graph displays or 64 independent LED. On which includes a B-type BCD encoder chip, multi-channel scanning loop, segment the word drive, but also an 8 8 static RAM for storing each data. Only one external register is used to set the segment current of each LED.2: 0.36" 4 digit led display 7 seg segment Common cathode Red3: The module is compatible of 5V / 3.3V microcontroller; Only three IO ports are used to drive the eight digit display.4: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 on5: Only three IO ports are used to drive the eight digit display. MAX7219 supports flicker free displays as well as cascading displays; PCV board four corners of the fixed copper stud, which can effectively precent short circuit accidents happenConnection: VCC?5VGND?GNDDIN ?P00CS ?P01CLK?P02Note: VCC and GND can not be reversed, otherwise it would burn the chip.Package Including:5 MAX7219 7-Segment LED matrix
Product Features
- 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.
