Nixie Board features Sockets for Nixie Tubes

Columns with separating Dots are optional for the Clock

Temperature sensor with jack 3.5 mm is optional for the Clock

Power Supply is optional for the Clock

Nixie Clock support usage of basic Accessory – Temperature sensor

The base listing does NOT contain Columns and Power supply.
These parts you need to select in options.
Also you can buy these items separately.

*The MCU board support a variety of tubes, such: ZM1042, Z522M, Z566M, Z5220M, ZM1040, Z5660M, B566M, LC-631, IN-14, IN-18, IN-12, IN-8, IN-7, IN-1, IN-2, IN-4, IN-8, IN-15, IN-16, IN-17. To use this tubes You need appropriate tubes PCB(s)

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.
