This versatile 6-digit Nixie tube clock mainboard is the perfect solution for DIY enthusiasts who want to create a custom, functional, and visually striking Nixie tube clock. The board integrates all essential components, including a high-efficiency boost module, ensuring that you can build a complete Nixie tube clock with minimal effort. Compatible with IN12, IN14, IN18, and QS30-1 Nixie tubes, this mainboard is designed for hobbyists and creators who value flexibility and precision in their projects.

What is it?

The 6-digit Nixie tube clock mainboard is the core component required to build a functional Nixie tube clock. Once you add your preferred Nixie tubes (IN12, IN14, IN18, or QS30-1), you'll have a fully operational clock. This DIY kit is designed to allow you to create a truly unique Nixie clock with the freedom to customize its features and appearance.

Key components include the DS3231M RTC (Real-Time Clock) with an integrated crystal oscillator for precise timekeeping, the MAX1771 boost converter for efficient voltage regulation, and the STC15W408AS microcontroller, which is equipped with built-in protection against cathode poisoning and features such as delayed shutdown and timed power on/off. With these components, you’ll get a reliable, customizable, and energy-efficient clock.

Why did we make it?

We designed this product to cater to the growing interest in retro tech and Nixie tube clocks, which are known for their nostalgic, vintage appeal. This mainboard gives hobbyists and DIY enthusiasts the opportunity to create their own Nixie tube clock with minimal complexity, thanks to its all-in-one design. We also wanted to address the need for a customizable and high-quality solution for Nixie clock creation, one that is easy to assemble and reliable for long-term use.

The integration of the DS3231M real-time clock module ensures that your timekeeping remains precise, while the MAX1771 boost converter ensures that the clock will work reliably with a wide range of Nixie tubes. Whether you're building the clock for personal use or as part of a creative project, this mainboard offers the flexibility and power you need to bring your vision to life.

Pre-Configured with All Necessary Components: The board comes with all the wiring and components you need to get started, including the necessary connectors and cables for the clock’s assembly.

The mainboard is ideal for those looking to dive into the world of Nixie tube clocks without having to design all the components from scratch. By integrating all essential functions into a single board, we make the process of building a Nixie clock accessible while offering the flexibility to customize the clock’s appearance and features.

Note

DIY Assembly Required

As this is a DIY kit, you will need to solder the Nixie tubes or tube sockets and build an enclosure. Basic soldering and DIY skills are required to complete the assembly.

Customization and Modifications

While the board is designed to work out of the box with minimal configuration, we encourage users to experiment with their own designs and modifications to make the clock truly their own.

Power Requirements

The clock requires a 9V or 12V DC power supply (0.6A or higher). A DC5.5-2.1 connector is used for the power input. Please note that a power supply is not included and needs to be purchased separately.

Wiring and Components

All necessary wires and connectors are included for assembly, making the build process straightforward. You’ll need to supply your own Nixie tubes and case for the final assembly.
