Nixie Tester Shield for Arduino

 Buy on eBay    

The kit allows you to drive any Nixie tube you want with an Arduino. It is a modular system consisting of a High Voltage Power Supply and a Socket Module on top depending on the type of Nixie tube. You can use the kit to getting started with Nixie tubes and to build, e.g., a one-digit clock or a simple counter.

The modules can be ordered bundled or seperatly, as PCB + components or as PCB only.

The Nixie tubes are not included and have to be purchased seperatly.


  • Compatible with Arduino UNO and MEGA
  • Modular system consisting of a High Voltage Power Supply and a Socket Module for different types of Nixie tubes
  • Very high efficiency using the MAX1771 switch-mode controller
  • Easy to build, no SMD parts
  • Programmable using the Arduino IDE

So far, Socket Modules for the following Nixie tubes are available:

There are more Socket Modules to come...

The kit comes with an printed assembly instruction and a detailed functional disctription. A preview of the instructions can be found here: Download PDF Instructions
The schematics and the functional discription are only providided when purchasing the kit.

The shield needs an Arduino UNO or MEGA to function. The sketches are uploaded using the Arduino IDE. The sample sketch to operate the Nixie tube shield can be downloaded from our GitHub repository: Download Sample Sketch

Safety Notes

This circuit design includes a switch-mode voltage converter which generates 170 V. DO NOT USE IF YOU DON'T KNOW HOW TO HANDLE HIGH VOLTAGES. You are responsible for the safety during the assembly and operation of this device.
