目前,各种电子报刊,杂志介绍用555制作各种实用电子电路真可说是五花八门,但是,电路板却是制作中的最大困难,本文介绍一种多功能555电路板可以基本适应不同制作的要求。而且自己可按照《电子制作》94年第3期介绍的方法一次小批量生产备用。在使用中可根据实际需要用小刀切断电路板,也可用细连接线连接。在制作时可根据实际情况做成:8×8、8×10、10 At present, all kinds of electronic newspapers and magazines introduced with 555 to produce a variety of practical electronic circuits can be said to be varied, but the circuit board is the biggest difficulty in production, this article describes a multi-function 555 circuit board can basically adapt to different production Claim. And in accordance with the “electronic production” 94 of the third introduced the method of a small batch production of spare. In use, according to the actual need to use a knife to cut off the circuit board, can also be connected with a thin cable. In production can be made according to the actual situation: 8 × 8,8 × 10,10
