From the project

A 6-digit IN-12B Nixie tube display and driver board designed in KiCad.

A 6-digit IN-12B Nixie tube display and driver board designed in KiCad.

This project is a modular Nixie tube driver board tailored for Russian IN-12B cold-cathode neon display tubes. It utilizes the HV5122PG high-voltage 32-channel shift register IC to drive tube cathodes with minimal microcontroller I/O pins, paired with individually driven RGB backlights underneath each tube.
