5V Ready-[HX3WE] High Voltage for Driving NIXIE tubes etc.

This is a small size module ,can light up 3~4 pcs if IN-14(or IN-12) nixie tubes with 15k resistor in serial,or 2pcs in-18 big nixie tubes with 7k5 resisotor in serial.

We use this module for driving out 3-tube IN-14 NIXIE Thermometer,4-tube IN-14 NIXIE Thermomete,4tube DIY IN-12 NIXIE clock,all work fine.

1.In SMD type,only one side of the PCB contains equipments,very thin.Half holes on left&right side for soldering on PCB as a PSU module on board,also contains Full holes for adding male/Female pins as plug-in module.
2.Please note that the EN pin in this SMD module is not an optional pin,please connect it with a MCU GPIO or connect it to +3V3/+5V to turn the Module power on(If can add a pull-up resistor (like 10k) to +3V3/+5V will be great);
3.With optional ADJ pin,can adjust the HV output with adding an extra resisotr,HV output adj. range in [~80V~~170V] range.if driving NIXIE tubes only,can connect ADJ pin to GND,the module will output ~170V;

DANGER! Lethal Potentials Present
THIS MODULE CONTAINS DANGEROUS, HIGH VOLTAGE POTENTIALS. USE CAUTION.
DO NOT TOUCH ANY PART OF THE MODULE WHEN IT IS WORKING.

Tips:
1. Standard 0.1"(2.54mm) pins, easy to be used, can use bread board or DuPont-Wires etc.
2. Please control the input current <=400mA for the low heat working state;
3. Module contains over current protection+soft boot-up. When over heat, the module will turn off, you need to re-power on to reset the module; 
4. We recommend working under 5V only,no over 6V.
5. More stable HV output, even for the heavy loader, the max output voltage only get a little bit drop;
6. If one module's power is not suited for your app,use two or more modules for driving the separated NIXIE tube(s) group,etc.;
7. Do not connect the modules' outputs in "Parallel Connection"!!!

Specifications(For reference only):

Module Size : 22mm(L)*11mm(W)*~6.4mm(H);
Module Pins : Half holes in 0.1"(2.54mm) std. gaps;
PCB Color : Black;
Freq: ~85kHz;

Pin Functions

*EN pin can be controlled by MCU GPIO[*3V3 or 5V MCUs are all fine]) directly,no need to add resistor in serial.

For 24*7 continually working condition, we recommend you control the input current less than 400mA when under 5V in, it keeps this module working under the low heat condition.

Typical Usage:
For driving NIXIE Tubes;
