Our Benefits:

• All our Nixie Tubes Clocks are using HV513WG chips,
  it provides higher brightness in multiplexing mode in comparison with HV5812 chip and greater reliability compared to legacy K155ID1
• We offer flexible Tubes Boards platform, that support many Nixie Tubes
  (out Tubes Boards designed for IN-4, IN-8, IN-8-2, IN-12, IN-14, IN-16, IN-17, IN-18 and Z573, Z5660M, ZM1042, Z568M Nixie Tubes)
• It is easy to build a beautiful Nixie Tubes Clock with our Boards, we also offer Acrylic, Wooden and Stone Cases for our Clocks
• Fast uploading pf the Firmware via USB to the Control Board
• All the latest version of the Firmwares to all our Nixie Clocks are always available on our GitHub channel
• No need for additional drivers, we are using only genuine USB-to-serial converters (FTDI),
  drivers for them are pre-installed in all popular OSes: Windows, MacOS, Linux
• It is easy to modify the Nixie Clock’s Firmware functions for your tasks due to the open Arduino platform
• We use High Quality PCBs and Components, also we use Japanese aluminum capacitors only for our Boards (Nichicon, Panasonic)
• Tubes Board is easy to modify by cutting if you want to build 4 Tubes Clock [HH:MM] from 6 Tubes Clock
• Our Nixie Boards use Power On Self-Test (POST): LED backlight flashing,Tubes flashing and Start up Tune. Our Boards use,
  Firmware version can be seen at the end of the POST test
• Our Tubes Boards use Unique detailed Tube test.
  Our soft test checks each Tubes segment on every Tube, it allows to see segments failures
• We provide competent technical support for all our products

Software Features:

• Support for many kinds of Nixie Tubes 8 tubes [HH:MM:SS:UU/Temp])
• Date format: 8 tubes [DD:MM:YYYY]; 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 of 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 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

Hardware Features:

• Special schematic that prevent “blue spot” effect inside IN-18 tubes.
• Full static displaying mode.
• No flickering.
• High brightness and contrast.
• Integrated High Voltage Power supply 150 – 220V.
• 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).
• High quality PCB and components. We use Japanese aluminum capacitors only (Nichicon, Panasonic).
• 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.
• 2 dots Column (digits separator) with independent controls for upper and lower dots.
• Power consumption: 12V, 1000mA (Recommended: 12 VDC, not less than 1A ).
• NCM109  MCU board size: 100 x 50mm  (world’s smallest dimension).
• NCT318 Tubes board  size: 264 x 50mm
• NCT818 Tubes board size: 94 x 50mm

*The MCU NCM Control Board support a variety of Tubes such as following.
Z-series: Z5660M, Z566M Red, ZM1042, ZM1040, Z5220M, Z522M, B566M, LC-631;
USSR:  IN-18, IN-14, IN-8, IN-8-2, IN-12, IN-4, IN-16, IN-15, IN-17, IN-7, IN-2, IN-1
To use these Tubes, you need appropriate Tubes Board
