We offer optional accessories for the Arduino Nixie Clock:

*The MCU board support a variety of tubes, such: ZM1042, Z522M, Z566M, Z5220M, ZM1040, Z5660M, B566M, LC-631; xUSSR’s types: IN-14, IN-18, IN-12, IN-8, IN-7, IN-1, IN-2, IN-4, IN-8-2, IN-15, IN-16, IN-17. To use these Tubes, you need appropriate PCB for tubes.
**4 tubes clock is available only on IN-18 (NCT218 boards), ZM1042, Z522M, Z566M, Z5220M, ZM1040, Z5660M series (NCT566 boards)

Our Benefits:

• A special Socket for each pin of IN-4 – easy to change Tubes.
• Easy to customize firmware under Your own needs, thanks to an open platform – Arduino.
• Fast uploading via USB.
• The latest version of the firmware always available on GitHub.
• No need to download drivers – we are use only Genuine USB to serial converters (FTDI FT230).
• Drivers for them pre-installed in all popular OS: Windows, MacOS, Linux.
• Human friendly menu.
• Very high qualty of Printed Circuit Boards.
• Japan alluminium capacitors.
• Power-On Self-Test.
• Competent Technical support.

Software Features:

• Clock support IN-4 Nixie Tubes (6 Tubes [HH:MM:SS] or 4 Tubes [HH:MM] format).
• Date format: 4 Tubes [DD:MM]; 6 Tubes [DD:MM:YY]; 12/24 hour mode.
• Slot Machine (Anti poisoning – tubes saving function. Increases the service life).
• Unique RGB LED backlight with 16,7 million colors. Your can choose any constant color off backlight LED and memorize it. Or you have option for a cyclic full spectrum color change!
• Switching on/off LED backlight in the matter of seconds.
• As alarm sound clock uses standard RTTTL (Nokia format) melodies, so you can easily to change it (included songs: Mission Impossible, We Wish You…).
• Easy updating firmware via USB using Arduino IDE.
• Software based on Arduino Sketch, so MCU has Arduino bootloader within.
• Power On Self-Test (POST): LED backlight, tubes and sound. You can check firmware version at the end. Unique detailed tube test – our soft check each segment on every lamp. Distinguishable to see segment failure.

Hardware Features:

• Integrated High Voltage Power supply 150 – 220V.
• ICSP connector for flashing Arduino Bootloader to blank MCU.
• 3 PWM channels for RGB LEDs 8 bit per channel = 24bit = 16,7 million colors. It can be disabled in the menu (please check the manual).
• Test points for testing, adjust and control low and high voltage circuits.
• Pads for internal buttons and terminals for external buttons.
• Pads for internal USB connector and terminals for external USB.
• Terminals for internal and external power connector.
• Terminals for external and internal buzzer.
• 4 dots (digits separator) with independent controls for upper and lower dots.
• Power consumption: 12V, 360 mA (Recommended: 12 VDC, not less than 1A ).
• NCM109  MCU board size: 100 x 50 mm  (world’s smallest dimension).
• NCT404 Tubes board size: 243 mm x 50 mm x 20 mm.
