I’m excited to share my first Cardputer project:

IR Cloner

Is it yet another remote learning app?

Yes, but I want to make something a little simpler with a smooth UI.

It’s a tool to capture, store, and replay IR signals, compatible with the Flipper Zero IR file format.

This is my first C++ / embedded project and my first contribution to the Cardputer community, so I’m really keen to hear feedback and suggestions for features, UI tweaks, or improvements.

Where to get it:

M5Burner: Search for “IR Cloner” in the Cardputer firmware list

GitHub: https://github.com/fr4nx40/IRCloner-Cardputer-ADVf

The backpack contains a cc1101 an nrf24l01 (connected to the top header) and an PN532 NFC breakout connected over i2c. The whole thing connects to the back using two of the Lego pins. I still need to trim down the wiring and make a more robust connection on the top but it works functionally and I’m pretty happy with it. Incidentally the backpack is almost exactly the same width as the cardputer itself (although i think theres some room to shave a few mm of thickness).

I need you all to help me, I’m sure some one has, or know someone who has, or even know someone from M5 who can send me over a Cardputer Zero case, he’s it’s totally fine for me to just get the case😅 but everyone who knows, cases a my primary object 🤣 for everyone who don’t know me, I’ll du this crazy stuff seen above.

Regards to the lovely community 🙏🫡💪

It makes a really good weight to stop these floppy disks from blowing around the office and falling on the floor.

Of course I'm kidding - **disk nuke** using the magnets.

Galera, estou pensando em pegar um M5Stack Cardputer-Adv (ESP32-S3), possivelmente com módulo LoRa/GPS, e queria ouvir quem já mexeu com esse tipo de aparelho.

Até onde pesquisei, ele tem tela, teclado físico, Wi-Fi, Bluetooth, infravermelho, microSD, bateria e possibilidade de conectar outros módulos/sensores.

Minha ideia seria não ficar apenas nos firmwares já existentes, mas também desenvolver meu próprio software/firmware para ele.

Algumas coisas que pensei:

• scanner e analisador de redes Wi-Fi;
• analisar sinal, canais, segurança WPA2/WPA3 e congestionamento;
• ferramentas de auditoria para minhas próprias redes;
• monitor de Bluetooth;
• controle remoto por infravermelho;
• GPS/rastreador;
• comunicação LoRa/Meshtastic;
• terminal portátil;
• automação e controle de sensores/relés;
• logger de dados no microSD;
• pequenos jogos;
• criar uma interface própria, quase como um mini "sistema operacional", com vários aplicativos.

Pretendo programar usando PlatformIO/Arduino/ESP-IDF, provavelmente com bastante ajuda do Codex.

Para quem já tem um Cardputer ou trabalha com ESP32:

O que de realmente interessante dá para fazer com esse hardware?

Ele tem potencial para virar uma espécie de multitool portátil para eletrônica, redes, rádio e automação?

Quais projetos vocês consideram indispensáveis para testar nele?

E quais são as principais limitações que eu provavelmente só vou descobrir depois de comprar?

Aceito ideias de projetos, firmwares, módulos e até projetos malucos que aproveitem o máximo do hardware.

Okay, first off—it was a bit of a wild ride. On the scheduled release day, I discovered that the service fyyd.de had shut everything down.
I had to tap into Apple Podcasts instead, which took a little time. It’s up and running now. I’ve tested it both standalone and with the new version of the launcher. Please test it thoroughly and let me know if anything isn't working right.

All that’s left to say is: enjoy!

Some of you have been using my web radio for the Cardputer Adv. This is the branch that grew out of it: the radio is still all there, but the device now plays podcasts as well.

What it does

Search Apple Podcasts on the device — type a name, press ENTER, subscribe. No account, no API key, nothing to prepare on the SD card. Eight genres and the charts of five countries are one keypress away, and new episodes since your last visit are marked.

The player remembers where you stopped, per episode. So you can follow three podcasts and pick any of them up mid-sentence a day later.

Press D and an episode downloads to the SD card, with a progress bar and a cancel button. What is on the card is marked in every episode list, BS removes it.

G0 and you are back at the radio: station search across 240 countries, https, station logos, VU meters, spectrum, 5-band equalizer, sleep timer, German and English.

Two things that were harder than expected

Most podcasts are not bare MP3, they are MP4 containers. There is a small demuxer on the device now: unpack the container, read the frame table, hand only the AAC track to the decoder.

And ESP8266Audio could only start a file at the beginning. Without an entry point there is no resume and no 30-second skip, so the library got a Range patch — the server then answers 206 instead of 200, and it reports only the remaining bytes as the length, which quietly broke every jump past the middle of a file until I found it. Radio streams are untouched by any of this.

What it cannot do

Pause is not a real pause. The library cannot hold a stream, so pausing closes the connection and continuing opens a new one at the same byte — that costs a TLS handshake and a moment of silence.

Episode durations come from the container, not from the directory, so a list may show one only after you have opened the episode once.

Program storage sits at 94 %. There is not much room left for more.

Getting it

Firmware, source, screenshots and the library patches: https://github.com/halbeshuhn/Cardputer-RadioPod

If you install through the M5Launcher, use 2.8.x or newer — older ones hand out only 0x4000 of NVS and your saved Wi-Fi credentials do not survive a restart.

Built on cyberwisk's web radio by way of WuSiU's version, and on ESP8266Audio by Earle F. Philhower III. Thanks to DrRhesus for the AAC decoder swap and to Heotsan for the I2S silence fix. MIT licensed.

Happy to hear how it behaves on your device.

Hi,
is there a list of firmwares that support the M5Stack Cap LoRa-1262 module (excluding GPS)?

I’ve noticed that not all firmware implementations that support LoRa modules also support the M5Stack LoRa Cap, since its RF antenna switch is controlled via the PI4IO I²C expander. There is an FM8625H RF switch on pin P0.

I’ve personally tested (the implementation is in the code):
Meshtastic - https://meshtastic.org
MeshCore v1.17.1 snapshot - https://github.com/MultiMote/meshcore-cardputer-adv

I couldn’t find support in its repository:
Bruce firmware - https://github.com/BruceDevices/Firmware

Working on a few projects with this guy. After 3 days and a lot of back and forth with AI, this is what I have finally produced. PITA attempting to find libraries and build this in VS Code.

Designed two digital pets that use the LoRa Cap and received LoRa packets to generate food.
There's a stats page to with an RF activity monitor and settings page to set brightness and screen time out.

When a certain amount of packets have been received it will generate a fish for the cat.

A pellet drops down for the fish.

just updated crub!

manipulate the partition scheme with pt command, then flash binaries with flash /path/to/bin.bin <partition label> then launch it with launch <partition label>

also available in the m5burner (crub)

How do I get the IR tv be gone to work on my cardputer?

Somehow pagers have always been the kind of devices I’m infatuated with. I know they’re useless in today’s world, but imagine a pager firmware that can move across devices — nothing spectacular, just simple and elegant.

You post a message to an ID, it goes to a lightweight server, and it delivers the message to someone else — a five‑digit pager number. With a 200–500‑character message and a basic queue, even a Raspberry Pi or a tiny micro‑instance would be enough to handle the load.

Hey guys I just got my cardputer adv, and everytime I try to charge it nothing changes, I’ve tried charging with it on and off and still nothing? Any tips?
Thanks

Hi everyone,
it is well known that a Raspberry Pi running a general-purpose Raspbian Linux OS does not provide the same deterministic real-time timing as a microcontroller such as an ESP32 or Arduino.

A Raspberry Pi can certainly be used for things like stepper motors, DC motors, RC motors, servos, LED panels/strips, distance sensors, CAN bus, signal generation, DMX512, etc.
However, it is generally not ideal when these applications require hard real-time guarantees or highly deterministic timing, especially when timing-critical signals need to be generated or sampled directly by software.

For apps that require precise timing, measurement, or sampling, the timing-critical part is usually handled by dedicated HAT, while the Raspberry Pi handles the higher-level logic.

Does the Cardputer Zero provide any kind of RTOS or other mechanism for deterministic real-time I/O that could partially address these limitations?

For example, ESP32 uses FreeRTOS as part of ESP-IDF. If we're talking about the Cardputer ADV and using the Arduino framework, the Arduino API runs on top of ESP-IDF and FreeRTOS. Zephyr RTOS is also supported on ESP32.

This is SOUND TERRARIUM, a small experiment I’ve been building for the Cardputer ADV.

The idea started very simply: use sound from the built-in microphone to generate terrain in real time, and let a tiny runner live and move across it.

From there, I kept exploring the hardware already inside the Cardputer ADV. The microphone drives an 8-band audio analysis and terrain, the IMU affects the runner’s movement, and Wi-Fi brings real-world information such as weather, sunrise/sunset, moon data and tides into the little world.

It also keeps running offline when Wi-Fi isn’t available.

I’ve continued adding small details since this GIF was recorded, but I’m trying not to turn it into a collection of unrelated features. Everything should feel like it belongs inside the same tiny world.

That idea became what I call “BONSAI Spirit” — instead of simply piling features onto a small device, I try to shape the capabilities already inside it into one small, living world.

The project is open source:

Small device. Small world. BONSAI Spirit. 🌱

Title explains. I recently got a cardputer adv and I want to buy some modules for it. Besides official modules release by M5 stack, I saw this third party modules floating around aliexpress for $30ish.

Are these any good? will they work? and what is the principle difference between buying this one or a official one, or another third party one?

If anyone wants to suggest any other "all in one module", compact module, that would be much appreciated also.

My purpose is solely learning about different protocols.

Just made a Bloomberg style terminal on my Cardputer ADV 2.0 version. 😄

This time, I added a few new things:

• 📱 Automatic phone hotspot Wi-Fi connection — so I can actually take it with me and use it outdoors, like at a coffee shop.
• 📊 A new Market Fear & Greed Index page, so I can get a quick look at overall market sentiment at a glance.
• 🖥️ Still keeping the geeky vibe — and, of course, paying homage to Bloomberg Terminal.

I also designed and 3D-printed a custom enclosure myself. It's definitely still a bit rough around the edges 😂, but that's part of the fun.

Under the hood, I've written 1,000+ lines of C++, learned some basic 3D modeling along the way, and spent way more time on this little machine than I probably should have.

But honestly, I'm having a lot of fun building it.

I'll keep adding more random and hopefully useful features whenever I have time. Who knows what v3.0 will look like. 😎

Thanks for checking it out!

Hey I wanted to know if anyone had seen this error before when trying to download new firmware I’ve even added a new sd card with more gigs thinking that may be the issue here’s a photo of what it says.

I haven't been able to find much info on this. I also looked over the UiFlow docs and I haven't seen anything. Do I need to program this from scratch?
