- SPU: AL-PRT3-73cishky[5]
- Custom processing: Yes
- Model: NE555 Pulse Module
一、本模塊適用範圍：
1.用作方波信號發生器，產生方波信號供實驗開發使用。
2.用來產生驅動步進電機驅動器的方波信號。
3.產生可調脈衝供MCU使用。
4.產生可調脈衝，控制相關的電路。
二、簡要說明：
1、尺寸：3.5CM*4.6CM
1、主要芯片：LM358；
2、輸入電壓:5V-12VDC。
3、輸入電流：≥100MA；
4、輸出幅度：接近於輸入電壓；
5、頻率調節範圍：0.07HZ-2KHZ（也就是周期在0.45毫秒到15秒左右）；
頻率調節方法：
板上有4個短路帽可以選擇頻率：
插0個短路帽，也就是4個短路帽全部取下，為高頻檔，周期最長調到0.3秒；
插1個短路帽，周期可以調到4秒左右；
插2個短路帽，周期可以調到7秒左右；
插3個短路帽，周期可以調到10秒左右；
插4個短路帽，周期可以調到15秒左右；
小電機；
三 優勢特點：
1、占空比和頻率分辨可調；
2、輸出帶LED指示，有沒有輸出直接明了（高電平時LED量，低電平LED滅，頻率比較低時LED閃爍，頻率高時LED會常亮，因為肉眼是分辨不出來的）；
