modname=ckeditor     This digital potentiometer has many advantages： 1、Control board and drive board are separated，Convenient for different requirements to form a variety of uses。 2、The driving board adopts1/4W 1%The precision metal film resistance forms the resistance network；adopt    8Two relays（2^8=256）The value of the resistance can be adjusted by changing the isolation on-off。And with    Hand in hand form of a number of single or multiple potentiometers to achieve    Combination of different circuit requirements。   3、The control board can generate256level9Group signal to drive board，And power off memory function。    The special four digit digital tube is used to display the current control relay's position number and position    Step value of each potentiometer。The operation part has coding switch operation or reservation    Press key。In addition, you can also pass theTTLControl of sending data through serial port。 4、DC8V-12Vpower supply，The current of single driving board is not more than0.23A。The current varies with the resistance    Changes will change accordingly。 5、Available throughTTLSerial port control。 6、Large quantity can be customized according to requirements。   parameter： Supply voltage--8-12V/DC;When multiple drive boards share one control board, they need to share one control board Power supply。 electric current------Single drive board<=0.23A;According to the number of drive boards when selecting power supplyx0.3A resistance------At present, the resistance of potentiometer is only 01.02k、2.04k、5.1k、10.2k、          20.4k、51k、102k、255k、510kOptional。 size------Control panel（65x40mm）Drive plate(65x85xhigh18mm)          Control board signal line500mm；Signal line for single drive board200mm          Digital tube0.36inch          Coding switch opening7mm；The length of the stem of the teeth is longer20mm          pcbthickness1.6mmCopper thickness1ounce Adjustable precision--（resistance/Adjustable precision）1.02k/4R；2.04k/8R；5.1k/20R；          10.2k/40R；20.4k/80R；51k/200R；102k/400R；          255k/1K；510k/2K Reset time-- <500mS                      TTLSerial port control： Baud rate--------115200 Check digit--------NONE Data bits--------8 Stop bit--------1 data format-----JSC*(1-9)=***(0-255) Examples-----------jsc1=001（"JSC"Regardless of case，The first potentiometer is set to001rank，                       The control panel will return after receiving the correct data Potentiometer:  1                                                                             degree:  001  ）       Digital tube display of rotary encoding switch in dimming mode1-8corresponding8Level brightness "-"The minus key is equivalent to the left rotation of the encoding switch"+"The plus key is equivalent to the right rotation of the encoding switch "M"Function key is equivalent to coding switch key，The reason for not matching these buttons is to cater to Different users have different requirements for key positions。Each key has soft anti shake processing and Press and lift detection，The program will make different judgments according to the duration of pressing the function key； If you press the plus minus key, you must release it before you press it once。
