QB051/QB090 4-Digit Tube Display Module

Product Introduction #

The four-bit ninumber module is a module for displaying digits, which integrates a 4-bit common-anode ninumber module, and uses the driver chip TM1650 to reduce the difficulty of wiring.

Each digit of the digital tube is composed of eight leds (including decimal points), by controlling the different positions of the LED light, you can make it display numbers, characters and symbols.

Application reference: Numerical visualization projects, such as temperature, humidity, counting and other scenes requiring digital display.

Parameter Specification #

Wiring Diagram #

Note：Expansion board is attached to esp32 controller board.

Sample Code #

#include 
#include 

TM1650 d;
void setup() {
Wire.begin(); //Join the bus as master
d.init();
d.displayOff(); 
}

void loop() {
char line[] = "1234";//Enter what you want to display
d.displayString(line);
d.displayOn();
}

Note: If you are using an Arduino board, then connect the CLK pin of the 4-Digit Tube Display Module to the PIN A5 of the Arduino and the DIO pin to the PIN A4 of the Arduino, and upload the program.

Test Result #

After uploading the code to the controller board, the four-digit nixie module will display 1234 in sequence.
