Description

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.
