自制按鍵式多功能測試儀 主板圖

測試儀主板線路圖  有時間自己也可以做一塊 臨時測試用 ，本來設(shè)計用三極管或者可控硅控制，但是這些半導(dǎo)體元件多多少少有內(nèi)阻，且影響電流的精確度，所以使用繼電器內(nèi)阻小，對電流精度影響甚微，這個測試儀除了按鈕和電流表是買來的，其他配件都是廢舊利用，，繼電器是從舊的空調(diào)電腦板上拆地，，對于家電維修的人來說不難找，4017價格2.5元 uln2003空調(diào)電腦板上也有，反正總成本40元左右！?。?！頂?shù)?0樓就免費發(fā)觸發(fā)電路圖！?。?！

樓下說付費看不到圖片?。。。?！現(xiàn)在開放圖片?。?！

哎啥東西都需要錢
可惜我沒錢

我也沒錢..............................

哎?。。。〖夹g(shù)貼?。?！既然兄弟們這么說?。?！那就10塊銷售?。?！呵呵??！頂?shù)?0樓就免費開放

好東西，值得學(xué)習(xí)啊
我頂頂
