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 so it distinguishable to see segments failures
• We provide competent technical support for all our products

Software Features:

• Clock support many kinds of Nixie tubes (6 tubes [hh:mm:ss] format and 4 tubes [hh:mm]).
• 12/24 hour format.
• Date format: DD:MM:YY
• Slote Machine (Ani poisoning)
• Unique RGB LEDs backlight with 16,7 millions colors.
• Very easy to switch LEDS off/on.
• As alarm sound clock uses standard RTTTL (Nokia format) melodies, so You can easy 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): LEDs test, tubes test, input voltage test, sound test.

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 millions colors. It can be disabled in the menu (see 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.
• 2 dots column with separate controls upper and lower dots.
• Power consumption: 11-14V, 360mA (Recommended power source: voltage 12V, current 1-2A).
• MCU board NCM109 has world smallest size: 100mmx50mm.
• Tubes board NCT408 size: 200mmx50mm.

*The MCU board support a variety of tubes, such: ZM1042, Z522M, Z566M, Z5220M, ZM1040, Z5660M, B566M, LC-631, IN-14, IN-18, IN-12, IV-8, IN-7, IN-1, IN-2, IN-4, IN-8, IN-15, IN-16, IN-17 in case if you build your own Tube boards.
