MAX7219 8-Digit Digital Tube Display Control Module Three IO for 3.3V 5V Microcontroller
Descriptions:
The MAX7219 is an integrated serial input/output common-cathode display driver that connects a microprocessor to an 8-bit digital 7-segment LED display. It can also be connected to a bar graph display or 64 separate LEDs. It includes an on-chip B-type BCD encoder, multi-channel scan loop, segment word driver, and an 8*8 static RAM to store each data. Only one external register is used to set the segment current of each LED.
A convenient four-wire serial interface can be connected to all common microprocessors. Each data can be addressed without having to overwrite all displays when updating. The MAX7219 also allows the user to choose to encode or not encode each data.
The entire device includes a 150μA low-power shutdown mode, analog and digital brightness control, a scan limit register that allows the user to display 1-8 bits of data, and a detection mode that allows all LEDs to illuminate.
Features:
- Only need 3 IO ports to drive this 8-digit digital tube! There is no flicker when the digital tube is displayed! Support cascading!
- The four corners of the PCB board are fixed by copper studs, which can effectively prevent accidents such as short circuits!
- The digital tube is a 0.36 inch integrated cathode digital tube.
- This module is compatible with 5V/3.3V MCU (51/AVR/STM32...)
Specifications:
Packing size: 120mm*80mm*8mm/4.72*3.15*3.15"
Packing weight: 12g
Notes:
1. Do not reverse the VCC and GND to avoid burning the chip.
2. The P0 port of the 51 MCU needs to be connected to a pull-up resistor. If your MCU does not have a pull-up resistor, you can connect the data cable to other p
