The Nixie Shield / HAT is a modular circuit board that piggyback onto your Raspberry Pi to install it with extra functionality. The Shield was designed according to Raspberry Pi HAT specification. The Nixie Shield allows an Raspberry Pi board to connect any Nixie tube you want to use in your projects. The HAT is compatible with Raspberry Pi: 1B+, 2B, 3B, ZERO, ZERO W.
Nixie HATFor better understanding on what the Nixie Tube Shield is about, please take a look on the video below.
Driving Nixie tube by Raspberry Pi is very simple. The Nixie Shield use only five Raspberry Pi pins. Take a look at the following code. More code examples you can find on GitHub.

Raspberry Nixie Shield Python Basic Example
The Nixie Shield is compatible with Raspberry Pi: 1B+, 2B, 3B, ZERO, ZERO W.
This example shows how to control any nixie tube with a Raspberry Pi using Nixie Shield
Nixie Shield uses five digital outputs to drive nixie tube.
Pin 29 as on/off (EN) line, 31, 33, 35, 37 as an address (A, B, C, D) of nixie tube digit/cathode.
This example code is in the public domain.
