Blue board:

1. The MAX7219 drive is displayed

2. Onboard two 0.36 inch 4-bit integrated common cathode digital tubes

3. Two or more modules can be cascaded

4. Four positioning holes with a diameter of 3.6mm

5. Module supply voltage DC3.3V or 5V

6. Module compatible with 5V/3.3V microcontroller (STC51/AVR/STM32)

Special note

1. Do not connect VCC to GND incorrectly to avoid burning chips.

2.51 Microcontroller PO port needs to be connected to the pull resistance, if your microcontroller is not connected to the pull resistance, you can connect the data line to other ports.

Green board:

Model: MAX7219

Color: Green board

Features: 150μA low power off mode, analog and digital brightness control, scan limit register allowing users to display 1-8 bit data, LED light detection mode.

Only three IO ports are needed to drive eight nixie tubes.

Fixed copper bolt four corner PCV plate, can effectively prevent short circuit accidents.

0.36 "four digital tube total negative LED.

Module support: 5v/3.3v microcontroller (51/AVR/STM32...)

Wiring instructions (for example, for a program, you can select any IO port definition that can be modified in the program) :

VCC → 5V

Ground to ground

DIN → P00

CS → P01

Clock → P02

Red Board:

100% brand new, high quality

Power supply: 5V

Material: PCB + electronic components

Size: 76*21*11mm/2.99*0.8*0.43"

Wiring instructions (program, for example, you can choose any IO port definition that can be modified in the program):

VCC→5V

GND ground →

DIN→P1.0

CS→P1.1

CLK→P1.2

Notice:

Do not reverse VCC and GND, so as not to burn the chip

The P0 port of the 51 microcontroller needs a pull-up resistor. If your device does not have a pull-up resistor, you can connect to the data lines of other ports.
