exixe is a miniature driver module for IN-12 and IN-14 Nixie tubes.

It aims to simplify Nixie tube related projects by eliminating the need for obscure vintage driver chips and multiplexing circuits. Instead, you can control every digit and the RGB backlight via SPI using only 3 wires and 1 line of code.

exixe is cheap, small and modular for easy integration. It is compatible with Arduino, Raspberry Pi, and virtually all embedded dev boards today.

I did a small production run of exixe modules, and now you can buy them directly on Tindie:

Compared to the traditional approach, exixe modules offers significant advantages:

• 2x4 cm (0.79x1.57 inches)
• Breadboard friendly
• Easy integration
• Reusable

• High speed, up to 24MHz SCLK
• Simple 16-byte command packet
• Available on virtually all embedded systems including Arduino and Raspberry Pi

• RGB backlight
• 128 brightness levels
• Hardware PWM on all cathodes and LEDs for smooth dimming and animations

• Optionally allows twice the cathode current
• For poisoned cathodes in second-hand tubes
• Before and after.

• Brighter display
• Longer tube life
• Simpler design
• Lower power consumption
