Our Benefits: All our Nixie Tubes Clocks are using HV5122PJ chips,it provides higher brightness in multiplexing mode in comparison with HV5812 chip and greater reliability compared to legacy K155ID1We 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 ClocksFast uploading pf the Firmware via USB to the Control BoardAll the latest version of the Firmwares to all our Nixie Clocks are always available on our GitHub channelNo 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, LinuxIt is easy to modify the Nixie Clock’s Firmware functions for your tasks due to the open Arduino platformWe 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 ClockOur 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 testOur Tubes Boards use Unique detailed Tube test – our soft test checks each Tubes segment on every Tube so it distinguishable to see segments failuresWe provide competent technical support for all our products 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, 360mA (Recommended: 12 VDC, not less than 1A ).NCM109 MCU board size: 100 x 50mm (world’s smallest dimension).NCT404 Tubes board size: 243 mm x 50 mm x 20 mm.
