Hello everyone, in this lesson we will learn the name of grounding and the symbol of grounding

2

00:00:08,800 --> 00:00:13,033

Common names for grounding are VSS and GND

3

00:00:13,566 --> 00:00:16,466

Among them, GND is used more

4

00:00:17,700 --> 00:00:24,366

For example, the chip on the right, its fourth pin name is GND

5

00:00:24,600 --> 00:00:29,266

Explain that the fourth pin is the ground pin of this chip

6

00:00:30,566 --> 00:00:34,000

Next, let's look at the symbol for grounding.

7

00:00:34,966 --> 00:00:41,100

In computer and mobile phone circuits, there are generally only two common symbols for grounding,

8

00:00:41,600 --> 00:00:46,233

and there is basically no difference in use.

9

00:00:47,800 --> 00:00:51,066

For example, in the picture on the right,

10

00:00:52,033 --> 00:00:57,266

a grounded circuit symbol is connected outside the ground pin of the chip
