00:00

Tear down. Review time. Got some uh Pi

00:02

Picos from AliExpress. At least they

00:04

claim to be Pi Picos. I think they're

00:06

fakes in some way, but they might be

00:07

usable. Uh I got two of them for $5.50

00:11

with free shipping from China to North

00:13

America. If I was to compare that to the

00:15

local distributor in my country, the

00:17

authorized dealer, they went $5.65 each,

00:19

which is, you know, not too much

00:20

difference money, but where they get

00:22

killed is the uh shipping and handling

00:24

almost 10 times as much on per unit

00:26

price. I try to buy them from my

00:27

country's distributors. So, um, now I'm

00:30

sure this is not an authorized product.

00:32

Uh, but here it is. Uh, but the

00:34

question, of course, is it's actually

00:36

usable or is it really truly an utter

00:38

fake and unusable? Let's, um, compare it

00:40

down to this is the real Pico, uh, from

00:42

an authorized distributor. Let's just

00:44

compare them. Uh, the silicon looks the

00:46

the really important silicon, the, uh,

00:49

custom design chip from Raspberry uh, is

00:53

here. Um, and it looks legitimate, but

00:54

we'll take it apart. Uh we'll run some

00:56

programs first, see if it acts the same,

00:58

and then we'll take it apart down to the

00:59

die level. Uh the memory chip is

01:02

definitely different. Uh we're going to

01:03

find some interesting uh native Chinese

01:05

supply chain vendors you probably never

01:07

heard of. Really big push by the Chinese

01:10

government right now to become

01:11

completely independent of Western

01:12

Silicon. Uh same thing with the power

01:14

spy regulator. Uh you can see it's

01:16

actually a different part. So they've

01:17

gone through the trouble of even though

01:19

it says copyright pipico. Um, and it

01:23

almost looked like the same traces.

01:24

They've gone in and opened up the design

01:26

files um, and modified it. You see the

01:29

power section is slightly different. So,

01:31

without further ado, let's uh, plug this

01:33

uh, this uh, fake in first, put a

01:36

program onto it, see if we have to run

01:37

something at least, see if it's useful,

01:39

and then we'll take the silicon down all
