AI Summary

The M5Stack Cardputer ADV can be significantly expanded using Pingqua's 'Hydra' style boards, which integrate both NRF24 and CC1101 modules for sub-GHz and 2.4GHz RF testing. Using the Bruce firmware, these boards allow for advanced spectrum analysis and RF functionality once the GPIO pins are manually configured via the web UI or SD card.

For hardware hackers and security researchers, these expansion boards transform a portable computer into a dual-band RF auditing tool comparable to a Flipper Zero but with a full keyboard and larger display.

Key points

  • Hardware Design and 'Cross Talk' — The video emphasizes choosing boards with antennas placed on opposite ends. Placing high-frequency antennas too close together causes 'cross talk' or noise, which significantly reduces the effective power and range of the radio modules.
  • Manual Pin Configuration in Bruce Firmware — Unlike typical peripherals, these boards require the user to edit the 'bruce_pins.conf' file. Key changes include setting CS to 13 and IO0 to 5 for the main board, and CS to 6 and IO to 4 for the NRF24 module.
  • Regional Frequency Tuning — The CC1101 modules come tuned for specific bands, typically 433 MHz (common in Europe/Asia) or 915 MHz (common in North America). Users must match their hardware purchase and firmware settings to their local regulatory requirements.
If you put both the modules and both antennas jammed in a tiny place, this creates what's called cross talk. Cross talk is just noise. Cal

Hi, welcome back to the channel. I'm

0:06

your pal Cal and today we'll be going

0:08

over the Carduter ADV again, except

0:10

we'll be going over something kind of

0:12

special using the Bruce firmware. With

0:14

the coming of the ADV having GPI opens,

0:16

this opened up a whole world of

0:17

opportunities for boards to be created

0:20

just like on the Flipper Zero. And with

0:22

those boards have come different

0:24

developers who've wanted to make cool

0:26

stuff. Now, it's rumored that M5 Stack

0:29

is making what's called a hacker board,

0:31

which is an RFID CC101 combo board, and

0:35

that sounds kind of exciting. But in the

0:37

meantime, we have some boards that have

0:39

come out by a company called Pingqua.

0:42

Pingqua. Pingqua. I hope I'm saying that

0:45

right. Now, Pingqua is a company that

0:46

makes Flipper zero boards, M5 stack

0:49

stick boards, as well as carder 1 and

0:52

ADV boards. And I kind of like their ADV

0:55

boards because they're pretty well

0:56

thought out. Their original board looked

0:59

like this where we have an NRF24 and a

1:02

CC101 on both sides. Now, there's

1:05

another board by a developer by the name

1:08

of Cassine, and I personally can't

1:10

really endorse that board. I don't like

1:12

how both radio modules are on the right

1:15

side of the board, as well as both

1:17

antennas being right next to each other.

1:20

This is a better design. Now, I'm not a

1:23

hardware expert, but I know damn well

1:26

that if you put both the modules and

1:28

both antennas jammed in a tiny place,

1:31

this creates what's called cross talk.

1:33

Cross talk is just noise. And I'm

1:35

willing to bet my bottom dollar that

1:37

that device has hella cross talk and you

1:41

will lose pretty much all the power when

1:43

it comes to the two RF modules that are

1:45

built into the board. Like, think about

1:47

it. Even if you use that board and you

1:49

see it going crazy, that's really

1:51

nothing. Like it looks like something's

1:53

there, but I don't think anything's

1:55

there. With this board, we can confirm

1:57

that both modules are working

2:00

beautifully. But you have to configure

2:02

them for it to actually work. This board

2:05

and this board are not hot swappable.

2:08

Now, this is the original Pingqua board

2:10

where we have a switch right there to

2:12

toggle between the nrf24 and the CC101.

2:16

Now, with their newer updated board, we

2:18

have the NRF24 and the CC101 with no

2:22

switch. So, as long as we change the pin

2:25

config, everything will work perfectly.

2:27

Now, quick disclaimer. If you're going

2:28

to buy one of these boards, please buy

2:30

them from their official website, which

2:31

I've linked down below. The reason why

2:33

I'm saying that is because there are

2:34

scalpers scalping for an insane amount

2:37

of money on AliExpress and Amazon. And

2:40

don't fall for that, please. They're

2:42

relatively inexpensive. and GPIO boards,

2:45

they go to support the creator. Now,

2:46

depending on what region of the world

2:48

you're in, you want to make sure that

2:49

the CC101s are tuned to the correct band

2:52

that you want. For example, this board

2:55

is tuned to 433, which works in my

2:58

favor. And this board is tuned [music]

3:00

to 915. This is their newer board. Their

3:03

newer boards have a 915 option. So, if

3:06

you need 915, well, I mean, you could

3:08

get both or you can get just one

3:12

specialized that you need. Either way,

3:14

remember when playing with CC101's and

3:16

NRF24s paired with an ESP32S3 that we

3:20

remember to only test our own hardware

3:22

and abide by the laws of our region.

3:25

This is something that's really

3:26

important and a lot of people take it

3:27

with a grain of salt. No, this is

3:29

serious, man. Some of these features are

3:31

educational and experimental, and if you

3:33

do the wrong thing in the wrong [music]

3:34

place, you could get in trouble. Now,

3:36

here we have one of the first iterations

3:38

of this board. We got two antennas on

3:39

opposite ends. We have the nrf24 here on

3:42

the right that is for the 2.4 GHz

3:44

spectrum and the CC101 tuned to 433 here

3:47

on the left as well as a switch to

3:49

toggle between them. Remember this is

3:51

not hot swap. We do have to go into the

3:53

Bruce config file and can uh you know

3:56

configurate the pins. Now over here we

3:58

have the newer Vinga board that comes

3:59

with a much longer CC101 antenna. Our

4:02

CC101 is tuned to 915 and our nrf24 is

4:08

tuned to 2.4 GHz. It works flawlessly

4:11

and I really do like this board. I do

4:14

like the option of being able to uh

4:15

switch between 433 and 915, but that's

4:18

just me. Now, we're going to go to

4:19

launcher since we have Pork Chop running

4:21

right now. We're going to click

4:22

Bruce.bin and install. And that will

4:25

install our firmware. Now, we're going

4:27

to head over to files. And once we go to

4:29

files, we want to go to Bruce web UI.

4:31

After we go to the Bruce web UI, you

4:33

want to connect it through your phone or

4:35

your desktop or you can connect your

4:37

card computer to your home network and

4:39

then access any computer to go to that

4:42

URL right here, which is bruce.local and

4:45

the IP is 172.0.0.1.

4:48

The username is admin and the password

4:51

is Bruce. Now, once you're in the file

4:52

system, you want to find Bruce pins.f.

4:57

Open that file and we're going to have

4:58

to change a few things in there. Now in

5:01

the Bruce pins con file we need to

5:04

adjust some values starting with CS

5:07

being 13. Next look for io0 and change

5:11

it to five. Now we scroll down till we

5:14

find nrf24. In nrf24 look for cs equals

5:19

and change it to six. Under nrf24 look

5:23

for IO and change it to four. Now, once

5:26

you've done all of that, make sure you

5:28

press save. Not save as, just save, and

5:31

then restart your device. But there's

5:33

another way that we can actually do it

5:34

just by clicking out the SD card from

5:37

the card computer. Now that we've got

5:38

the pins configured, we can switch this

5:40

on to the right to 2.4. Click next and

5:44

look for nrf24.

5:46

There we go.

5:48

And from nrf24, we're going to click on

5:50

spectrum. And there you have it.

5:54

That's actually really nice and a

5:56

powerful NRF24. Now, we can also plug in

5:59

the newer Pingqua NRF CC101 and we can

6:02

test it and it'll work straight off the

6:04

rip. But we don't have to switch between

6:06

2.4 GHz or the CC101 anymore. Going to

6:10

go straight to NRF24. Go to spectrum and

6:13

it's even better. Now, if you want the

6:15

CC101 to work for RF functionalities,

6:17

you want to go into RF, then config, and

6:20

in config, click CC101. But you do want

6:24

to keep something in mind. If you have

6:25

this newer board with no switch and you

6:28

have a 915 CC101, you want to specify

6:31

that you want it working for the 915

6:34

band. If you have a CC101 like the older

6:37

one tuned to 433, then specify for 433.

6:41

Keep that in mind. If you're enjoying

6:43

using custom firmware like the Bruise

6:44

firmware, M5 Pork Chop, Just Call Me

6:46

Koko's Marauder, or the Evil M5 project,

6:49

make sure that you support your

6:50

developers and give them a star if you

6:52

visit their GitHub page. They've put a

6:54

lot of time and effort into giving us

6:56

and inspiring so many people while also

6:59

educating them in a really fun way. If

7:01

you enjoyed this video, make sure you

7:03

like, share, subscribe. It helps the

7:04

algorithm and it helps me and I'd

7:06

appreciate it. Also, there's a referral

7:09

link for the card Peter ADV down in the

7:11

description. and it's 5% off and it's

7:13

all I could do. But hey, there's also a

7:15

link for the card Peter ADV Laura Cap

7:18

down below as well, which GPS modules

7:20

powered by the ATGM 336 man, which is an

7:23

very reliable GPS by the way. I've also

7:26

linked the Pingqua boards down below and

7:29

the ESP32 drivers, the GitHub pages for

7:32

Bruce. I've linked everything.

7:34

Everything is down below and I hope you

7:36

guys enjoyed because I love you guys.

7:38

We'll see you next time.
