SmartNixie Family Description
      The TES SmartNixie is a ready to use display module pre-programmed with several useful operating modes.  The on board processor reads a four position DIP switch at boot up to configure itself as one of 112 possible I2C slaves or any of several special modes such as the I2C master of a digital clock.  Modules are 100% interchangeable so that they may be alternated in the user application to maximize tube life especially when installed into 0.100" pitch socket strips which eliminates the need to solder directly to the module pins (See table at bottom of page).  The ICSP (In Circuit Serial Programming) connections to the PIC16F677 processor are also brought out on the module pins to allow for user programming of the processor flash memory when all DIP switches are in the off position (See warranty information below).

       The companion high voltage power supplies are very high density switchmode converters using a flyback transformer which provides tolerance of output short circuits as there is no direct input-to-output current path.  The switcher controller runs at a nominal 300 kHz (220-360 kHz) and can be synchronized to an external clock via the enable pin to frequencies between 370 and 500 kHz.  Input current during shut-down is 40uA Max. See the comparison chart for module size and power density versus other modules.
