00:00:00,266 --> 00:00:07,566

Hello everyone, today we are going to learn about A1466, A1465, A1502 mainboards

2

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

First take a look at the A1465 mainboard

3

00:00:17,066 --> 00:00:22,066

This mainboard uses Intel's fourth generation Core processor, which is low power

4

00:00:24,333 --> 00:00:26,533

This is a solid state drive slot,

5

00:00:27,600 --> 00:00:29,700

and this is a WIFI Bluetooth slot

6

00:00:33,333 --> 00:00:36,100

This is the power port, connecting the board

7

00:00:39,700 --> 00:00:41,033

This is a fan port

8

00:00:41,766 --> 00:00:46,000

These are the CPU power supply circuits that supply power to the CPU

9

00:00:46,800 --> 00:00:50,333

Here is a battery port and a backlight cable port for the keyboard

10

00:00:54,866 --> 00:00:57,800

Inside the shield, this is the lightning chip,

11

00:00:58,933 --> 00:01:01,033

and this is the screen cable port

12

00:01:01,566 --> 00:01:04,266

There are several white labels on the mainboard

13

00:01:04,666 --> 00:01:06,466

This is a waterproof label

14

00:01:06,833 --> 00:01:10,900

As long as the mainboard enters the water, the white will turn red

15

00:01:11,566 --> 00:01:14,766

There is a seat that connects the keyboard and the touchpad

16

00:01:19,333 --> 00:01:24,433

This is the back of the mainboard, which has the EC, which has 4 memory chips

17

00:01:27,066 --> 00:01:28,633

There's a memory next to it,

18

00:01:29,033 --> 00:01:32,633

but it's not for the CPU, it's for the chip next to it

19

00:01:36,500 --> 00:01:38,400

The chip is called the camera chip,

20

00:01:39,100 --> 00:01:41,400

and it processes images for the camera

21

00:01:42,366 --> 00:01:46,700

Here is a BIOS chip, and here is a CPU power supply control chip,

22

00:01:47,066 --> 00:01:49,233

which is the CPU power management chip

23

00:01:51,500 --> 00:01:57,133

The mainboard A1466 is basically the same configuration as the A1465

24

00:01:57,800 --> 00:02:00,366

There is a cable connector on this small board,

25

00:02:00,766 --> 00:02:03,266

and it's connected to this side by a cable

26

00:02:03,933 --> 00:02:05,866

This is just the power port

27

00:02:10,766 --> 00:02:16,533

This is a solid state drive, this is the main controller on the hard drive,

28

00:02:16,866 --> 00:02:19,300

and these are the memory chips next to it

29

00:02:20,200 --> 00:02:24,266

It uses Intel's 4th and 5th generation Core processors

30

00:02:24,900 --> 00:02:27,500

Over here is a WIFI Bluetooth module

31

00:02:28,566 --> 00:02:33,133

Inside this shield, there is a lightning chip that manages the lightning port

32

00:02:34,033 --> 00:02:35,900

This is the screen interface,

33

00:02:37,666 --> 00:02:41,933

and the inductor next to it is dedicated to supplying power to the backlight

34

00:02:43,433 --> 00:02:48,033

The screen backlight power supply circuit and boost circuit are all on the mainboard

35

00:02:49,966 --> 00:02:52,366

The back of the mainboard has a boost chip,

36

00:02:52,800 --> 00:02:56,333

a PWM chip that manages the backlight boost circuit

37

00:02:57,666 --> 00:03:01,966

There's an EC over here, there's a BIOS chip over here

38

00:03:03,966 --> 00:03:08,066

There are 4 memory chips on the bottom, as well as a camera chip

39

00:03:08,833 --> 00:03:11,533

There's also a memory chip next to the camera chip

40

00:03:12,333 --> 00:03:14,933

This is the A1466 mainboard

41

00:03:19,400 --> 00:03:24,066

Both the A1466 and A1465 belong to the MacBook Air

42

00:03:24,500 --> 00:03:27,666

This A1502 belongs to the MacBook Pro

43

00:03:28,000 --> 00:03:29,566

The mainboard wasn't removed

44

00:03:29,866 --> 00:03:31,200

It's a whole machine

45

00:03:31,700 --> 00:03:34,233

At the bottom of this battery is the touchpad,

46

00:03:35,166 --> 00:03:42,333

which has a touch IC, a keyboard controller, a FLASH, and some gravity sensing sensors

47

00:03:44,833 --> 00:03:49,333

There are 16 memory chips here, there are 16 on the back of the mainboard,

48

00:03:49,566 --> 00:03:51,966

a total of 32 memory chips

49

00:03:54,366 --> 00:03:56,800

Its memory capacity is relatively large

50

00:03:58,466 --> 00:04:02,966

The CPU is the fourth and fifth generation of Intel Core processor

51

00:04:05,233 --> 00:04:07,766

This is a solid state drive over here,

52

00:04:08,433 --> 00:04:12,333

and next to it is a screen port, and we can see this line

53

00:04:13,133 --> 00:04:16,600

There's a speaker port that connects to the speaker next to it

54

00:04:18,233 --> 00:04:22,400

There is a connector here, connected to this small board over here

55

00:04:22,933 --> 00:04:26,100

The WIFI Bluetooth module is not plugged into the mainboard,

56

00:04:26,666 --> 00:04:28,566

but into the small board here

57

00:04:29,266 --> 00:04:30,966

The power port is over here

58

00:04:31,400 --> 00:04:34,566

Okay, this is the mainboard of the A1502
