100% Brand new and high quality.
MAX7219 digital display control module.
This module is compatible with 5V and 3.3V microcontrollers.
You you can use it for Arduino.
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.
Only three IO ports are used to drive the eight digit display.
MAX7219 supports flicker free displays as well as cascading displays.
Wiring instructions(for example, it can connect any IO port,modified the Port Definition in the program):
VCC: 5V
GND: GND
DIN: P00
CS: P01
CLK: P02
Note:
VCC and GND should not be connected reversed, so as not to burn the chip.
