Hello everyone, let's take a look at the Apple mainboards A2337, A2338

2

00:00:07,933 --> 00:00:11,466

The A2337 mainboard looks like this

3

00:00:12,900 --> 00:00:15,633

It uses Apple's own M1 processor

4

00:00:20,000 --> 00:00:23,200

There are two memory chips on the top of the CPU,

5

00:00:24,366 --> 00:00:27,733

which means that the memory cannot be replaced directly

6

00:00:30,200 --> 00:00:33,033

There are two power chips next to the CPU,

7

00:00:33,400 --> 00:00:36,133

the main power supply and the secondary power supply

8

00:00:36,566 --> 00:00:41,766

They are responsible for output power supply to the CPU to provide working conditions

9

00:00:43,866 --> 00:00:45,566

These two are hard drives

10

00:00:46,133 --> 00:00:48,366

This is the WIFI Bluetooth module

11

00:00:49,633 --> 00:00:53,166

There are three inductors here, all 3.8V

12

00:00:54,400 --> 00:01:00,633

In the maintenance, we can also directly add 5V DC voltage to the three inductors,

13

00:01:00,866 --> 00:01:03,333

which can also be turned on and displayed

14

00:01:07,833 --> 00:01:13,366

Next to it is the inductor of the keyboard backlight, which is the backlight boost circuit

15

00:01:14,100 --> 00:01:17,866

The next big inductor is the power supply for the screen backlight

16

00:01:18,666 --> 00:01:21,800

This boost inductor is the common point boost inductor

17

00:01:22,800 --> 00:01:27,900

And then on the bottom are some of its PWM chips, the lightning chip

18

00:01:29,166 --> 00:01:31,433

These are Intel's lightning chips,

19

00:01:32,933 --> 00:01:35,133

which manage the Type-C interface

20

00:01:36,400 --> 00:01:41,133

On the back of this interface, there are two CD3217s,

21

00:01:41,200 --> 00:01:46,500

which we call USB-C controllers, also known as Type-C controllers

22

00:01:49,733 --> 00:01:54,333

On the back of the CPU, there is a 64 megabit BIOS chip,

23

00:01:54,533 --> 00:01:58,366

a code chip, a security chip, and so on

24

00:01:59,433 --> 00:02:02,133

The power consumption of this mainboard is very low,

25

00:02:02,766 --> 00:02:05,866

basically the power consumption of a tablet computer

26

00:02:07,100 --> 00:02:09,866

It has a radiator, but no CPU fan

27

00:02:13,866 --> 00:02:16,633

This is the mainboard A2338

28

00:02:17,000 --> 00:02:21,100

The overall structure is the same as that of A2337

29

00:02:21,633 --> 00:02:26,433

It also uses an M1 processor, two hard disk chips on the side,

30

00:02:30,766 --> 00:02:33,300

and a WIFI Bluetooth module on the bottom

31

00:02:33,766 --> 00:02:38,233

This mainboard uses the M1 processor, there is no T2 chip,

32

00:02:40,466 --> 00:02:44,666

no EC and no hard disk master, all the CPU management

33

00:02:47,066 --> 00:02:49,033

There are two power chips nearby,

34

00:02:49,366 --> 00:02:52,000

the main power supply and the secondary power supply,

35

00:02:52,766 --> 00:02:56,933

both of which provide working conditions for the hard disk and the CPU

36

00:02:59,133 --> 00:03:05,133

There are two Thunder chips on the side and two CD3217s on the back of the Thunder chip

37

00:03:05,766 --> 00:03:07,400

This is the screen port,

38

00:03:08,900 --> 00:03:11,333

and this is the display power controller

39

00:03:12,900 --> 00:03:21,033

There are also security chips, MOS tubes for charging and discharging batteries, and a 64-megabit BIOS chip

40

00:03:21,866 --> 00:03:23,566

This is the charging chip

41

00:03:26,700 --> 00:03:31,466

Okay, this is the mainboard of A2337 and A2338
