pros and cons

Pros

Neat, well-made, and portable.
Has a large, progressive support and improvement community.
Very competitively priced.

Cons

Quite a steep learning curve.
Doesn't comparison to a Raspberry Pi aliases Flipper Zero.

Mention a machine you tin fresh into your pocket, and group look to person 1 of 2 reactions:

They either opportunity "So, it's for illustration a Raspberry Pi!" Or they opportunity "Ahhh, it's much for illustration a Flipper Zero!"

Also: The Flipper One whitethorn beryllium nan eventual Linux PC for hackers successful 2026 - and I'm excited

When talking astir nan M5stack Cardputer Adv, it's really for illustration both. But also, neither. What nan M5Stack is for certain, however, is simply a absorbing spot of kit for anyone who wants to get their hands dirty.

So, what is it?

Hardware-wise, nan Cardputer Adv is simply a pouch machine that's nan size of a stack of in installments cards (over 20 cards, truthful we're talking a Warren Buffett stack here) that comes complete pinch a keyboard and a teeny-tiny display.

The Cardputer Adv is arsenic heavy arsenic a stack of in installments cards.

It's a strategy that's built to grip accelerated prototyping, business control, and location control, and is built astir a module called an M5Stack Stamp-S3A core; a low-power, dual-core, Wi-Fi and Bluetooth 5.0 low-energy tin system-on-a-chip. That intends that if we wanted to comparison nan Cardputer Adv to anything, it would beryllium nan Raspberry Pi 400/500 systems. In essence, it's a computing module that's been attached to a keyboard.

Also: I utilized a $4 timer to reboot my router, and it really made my net faster

There's a batch built into this this package. The keyboard has a afloat 56 keys that are amazingly usable (even by personification who has a touch of peripheral neuropathy), and nan show is simply a 1.14" colour LCD sheet that's amazingly readable. There's besides a ES8311 audio codec subsystem, a precocious SNR (signal-to-noise ratio) MEMS (Micro-Electro-Mechanical Systems) microphone, and a 3.5mm jack handling nan audio.

In addition, there's a six-axis inertial measurement portion (IMU) sensor, an IR emitter for beaming information astatine TVs and devices that tin beryllium controlled pinch a remote, a microSD paper slot for adding much storage, a 0-4P Grove port and an EXT 2.54-14P description bus for interfacing pinch outer devices and peripherals.

But there's more. The guidelines contains magnets truthful nan Cardputer tin beryllium stuck to a ferrous surface, and location are holes that are LEGO compatible for integrating nan Cardputer pinch your build projects.

Oh, and there's a lanyard hole.

Powering nan full package is simply a 1,750mAh Li-ion battery, which is beautiful hefty for a package of this size. It's a really compact, neat spot of kit. It's besides covered successful graphics explaining nan usability of different parts of nan system, different neat touch, and fits successful pinch nan creation artistic of different M5Stack products.

What tin it do?

Out of nan box, you've sewage a action of things to play with, from accessing nan six-axis mobility sensor advertisement IR emitter, scan for Wi-Fi channels, grounds audio, GPS receiver, LoRaChat long-range radio, and more. These are beautiful basal apps, mostly to get you started pinch nan system. If you do a speedy net search, you'll find a load much apps that you tin download and instal (here are some to get you started).

The built-in apps are a awesome measurement to get utilized to nan Cardputer Adv.

One point that you will request to get acquainted pinch is nan M5Burner app used to upload apps and codification to nan Cardputer Adv. It tin return a small spot of fiddling to get nan app moving (I had immoderate flimsy headaches getting it to activity connected nan Mac and needed to download drivers), but this is portion of nan learning, and it helps you get acquainted pinch nan full online support community.

Where nan Cardputer Adv really comes into play is erstwhile you want to commencement programming things yourself. You tin usage M5Stack's ain UIFlow 2.0 integrated improvement environment, aliases you tin usage Arduino. Here originates yet different learning curve. How steep that is depends connected really overmuch inheritance you person successful immoderate programming, and what your aspirations are.

I emotion nan creation of nan Cardputer Adv.

I propose starting mini and moving up from location truthful you don't get overwhelmed. Like pinch a caller Raspberry Pi aliases Arduino, you'll soon beryllium doing things that amaze you.

Cardputer Adv vs. Raspberry Pi vs. Flipper Zero

A mobility I've seen a batch is whether personification should get a Cardputer Adv, a Raspberry Pi, aliases a Flipper Zero. Let's tackle nan Flipper Zero comparison first.

Yes, nan Cardputer Adv is rather a cool tool, and there's nary uncertainty that it could beryllium utilized for ethical hacking tasks. But it's important to beryllium alert of nan hardware limitations.

Also: I hid 4 Bluetooth trackers (including AirTags) to trial their reliability - here's really Android rivals compared

For example, nan IR is emitter only, truthful dissimilar nan Zero, it can't beryllium utilized to clone remotes. Also, there's nary sub-GHz aliases NFC/RFID support, and there's nary USB-RS232 support, truthful nan Cardputer Adv can't enactment arsenic a keyboard. And while nan Cardputer Adv does person Bluetooth support that rivals that of nan Zero, nan package support connected nan Zero is acold better.

One point that nan Cardputer Adv does person that nan Zero does not is out-of-the-box Wi-Fi support. I did negociate to get Marauder Wi-Fi information scanner package to tally connected it, but it took a adjacent spot of Googling.

The Raspberry Pi is besides a very different animal. It's very mature and has an tremendous personification base. It's a acold easier level to get started with, but that's because you're booting into a afloat operating strategy and tin usage a big-boy keyboard and display.

I thin to deliberation of nan Cardputer Adv arsenic much on nan lines of nan Adafruit HUZZAH32, which is simply a instrumentality for either developers wanting a compact level to tally Arduino code, aliases a level to safely study Arduino programming.

Also: I recovered an M.2 dock that handles SSD cloning without a machine - and pinch only 1 click

Cardputer Adv is besides fun, and nan organization astir it is rather vibrant, active, and supportive of newbies based connected what I've seen (something that sadly can't beryllium said of nan Raspberry Pi organization astatine times).

ZDNET's buying advice

The M5Stamp Cardputer Adv is besides cheap, costing astir $42, which is nan benignant of value that you tin prime up a 1GB Raspberry Pi 5 for nowadays. You tin besides prime up accessories for nan Cardputer Adv, for illustration nan hardware for mounting up a Meshtastic open-source, off-grid LoRa-based connection platform for astir $30.

All this talk of integrated improvement situation and downloading drivers mightiness make nan Cardputer Adv look complicated, and to beryllium honest, compared to astir modern gadgets -- it is. But it's besides fun, and tin beryllium nan catalyst for immoderate beautiful heavy learning.
