AA battery driveable QS30-1 NIXIE Module for Arduino / AVR / PIC / STM / ARM /PI V1.0.
Notice:
In order to drive the NIXIE module, some internal equipments are under the High Voltage(up to 180V DC),please do not use this module outside or in any wet conditions,please do not touch any part inside the module when power supply is turned on.Always keep it away from kids.
Specifications:
Tube Name:QS30-1(FENGGUANG);
Module Supply: 2V~7V DC;
Max Current: <=150mA;
Module Size:38mm(L)*38mm(W)*43mm(H);
PCB Size:38mm*38mm;
PCB Color:Black;
Weight:38g;
The module works with 2 AA batteries (in serial),and also works with any standard USB power supply,use only high-quality adapter!
Features:
1).Very small size module,only 38mm*38mm,fits for a lot of tiny EE works;
2).Wild supply range,works fine with any 5V USB powered ARDUINO or other 5V/3V3 MCUs ,easy to be used. For driving less than 5 modules together,can connect to your computer's USB plugs directly.(For working under 3V,the Blue/Green LED may not be able to light up,but the NIXIE tube and red led work fine).
3).High effenciency design,low current.Usually one module needs only about 100mA current under 5V DC supply,so for 1~8 modules can be drived together via regular Dupont Line.For driving over 4 modules together,recommand you using a 5V/1A USB adapter.
4).Module contains a self testing switch,when press the test key down,the NUM-"8" will light up,easy for tesing the module.
5).74HC595 driving chips,simple 3-wire SPI interface,with /OE and HVEN pins,can adjust the global brightness via PWM signal and shutdown the High Voltage completely.
6).Contains over-current protection, and reverse connection protection circuits.
7).With 2 dots on the right and left side,you can create not only the NIXIE clock app but also the "Divergence Meter" from the Steins' Gate style looking with 8 modules.
8).Open source ARDUINO NUO source code,provide high level nixie_printf() function,easy to be used,can control the left and right dots in this function either.
9).We provide extra 1PCS acrylic back board for connecting 2,4,6,8,10 modules together for free.
10).Tri-colored RGB LED mounted under the NIXIE tube.
11).Beautiful CAD designed acrylic casemade using a laser cutter makes the module look beautiful. You can assamble/disassamble the case by using only 4 screws on the bottom/top of the case.

简单介绍一下尺寸与功能:
1、外观尺寸为38mm(L)*38mm(W)*40mm(H);
2、供电规格:2V~7V全兼容,推荐5V工作;单模块消耗电流约100mA(5V)。在3V以下供电时,LED中的蓝色与绿色无法点亮,但是红色LED与辉光管工作正常;
3、简单的双74HC595驱动方案,总共7根外接线,分别是:
+5V 电源
GND 地
DAT 数据
CLK 时钟
LATCH 锁存
/OE 输出有效
HVEN 高压有效
最小只需要三根IO线即可驱动(DAT,CLK,LATCH),/OE与HVEN可以忽略不接。也可以通过PWM信号控制/OE线来控制整体亮度,HVEN线则可以完全控制开启/关闭高压部分;
普通ARDUINO UNO即可控制,通常一个PC提供的单USB口可提供5V 500mA供电,使用普通杜邦线即可直接控制4只显示模块串联工作。经过2星期的程序测试,在LED全显示,NIXIE管道最高亮度情况下,4联模块程序工作,完全没有任何问题,除LED与显示管外,无任何零件有发热现象。
(图片内的四联板即为使用普通ARDUINO UNO直连电脑驱动的)
4.全部QS30-1显示管使用的都是从上千只管中精选出来的最高质量的风光管,确保显示的完美,绝无笔画断开、显示不全、显示暗淡等现象(绝非通过后期高压大电流自行“修复”的低寿命管子),同时配合高效率的升压电路,从根本上确保了绝对完美的辉光显示效果;
5、提供2联、4联、6联、8联背板,可以固定连接不同数量需求的模块组,在整体模块数量超过6只但是不超过10只的情况下,可简单换用外部5V 1A的USB电源适配器供电即可正常工作,不需要使用特殊的供电设备;
6、所有模块全部自带过电保护及电源反接保护电路,反接与过流都不会烧坏电路;
7、除QS30-1外,还在管子的左右侧各增加了一个点号,总共提供12个显示段,不仅可以完成如时钟、数字等的显示模块功能,只要组合8个模块,也可以完成“命运石之门”(原名:Steins;Gate;日语:シュタインズ・ゲート)中的“世界线变动率探测仪(Divergence Meter)”显示效果,届时会免费提供对应的源程序;
8、提供完整的ARDUINO UNO驱动源程序,支持高级nixie_printf()函数,用户可直接使用与printf()函数相同的规格参数简单地完成显示操作,可直接在参数中控制左右的点号,无需使用另外的函数。例如下图中的循环数字显示效果的输出函数为:
for (i=0; i<=9999; i++)
{
nixie_printf("%02d.%02d", i/100, i%100);
delay(50);
}
即可循环显示从00.00到99.99
应用代码就是这么简单;
