Stemedu 5PCS MAX7219 8-Digital 7-Segment Display Module LED Display Tube for Arduino MCU/51/AVR/STM32 Raspberry Pi ESP8266 Nodemcu

• 🚩 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
• 🚩 The module is compatible of 5V / 3.3V microcontroller; 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 prevent short circuit accidents happen
• 🚩 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
• 🚩 If any question, how to email us? Please click "Stemedu" (you can find "Sold by Stemedu" under Buy Now button), in the new page, click "Ask a question" to email us. ▶ Compatible with Arduino; And this requires the LedControl library to be installed – https(:)//github(dot)com/wayoda/LedControl

Description: 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. Display: 0.36" 4 digit led display 7 seg segment Common cathode Red Power: 5V Material: PCB + Electronic Components Size: 82 * 15 * 18mm Color: Red Wiring instructions (a program, for example, you can pick any IO port definition can be modified in the program): VCC: 5V,GND: GND, DIN: P00, CS: P01, CLK: P02 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 Connection VCC is connected to the 5V pin GND is connected to the GND pin Pin 12 is connected to the DIN pin Pin 11 is connected to the CLK pin Pin 10 is connected to the CS pin Package Included: 5 X MAX7219 Module 5 X 5P Straight Pin 5 X 5P Bent Pin
