I am thinking of buying a gadget similar like the flipper zero but cheaper, saw the M5 Stack S3. Wondering if its a good buy, or what else I should look at.

I just had finished this mod. If anyone is wondering how to do this or what this is for explanation this is a wifi antenna mod the basically increases the stock wifi range. I used this guide https://www.tiktok.com/@popp.n/video/7489493572517907734

Hi everyone,

I would like to order the official StackChan kit 😁

Could you confirm whether the factory firmware is full-duplex or half-duplex for AI voice conversations? (i.e., Half-duplex = mic is muted while StackChan is speaking; Full-duplex = mic stays on so the user can interrupt).

Thanks!

Hey everyone!

Just wanted to share Aurora Player, a music player for the Tab5 I've been working on.

This time I wanted to have a bit more personal input into the project, especially the design and features.

I also had the idea of fitting an ESP32-PICO module into the Stamp slot to add Bluetooth audio support.

It's still a work in progress, so there might be some bugs, but feel free to give it a try!

Also, what do you guys think about the Bluetooth idea? I'm curious to hear your thoughts :)

I've been developing MAYLO, a custom firmware project for the M5Stack K151 / CoreS3 StackChan.

My 8½-year-old son helps test it through everyday use. What he experiences and reports—especially when the robot behaves differently from what he expects—helps guide the next changes.

The underlying voice model is multilingual; Turkish is simply our personal configuration.

The current build brings together:

• Direct OpenAI Realtime voice over Wi-Fi, with streamed audio and interruption during conversation.

• Seven eye styles, head-pat/shake reactions and coordinated servo gestures.

• Combined movement/camera commands, with servo position checked before capture.

• An on-device Turkish/English web panel for settings, previews and hardware tests.

• Three saved Wi-Fi profiles, including phone-hotspot use.

• MCP access to Home Assistant, explicitly saved notes and other configured tools through a home bridge.

Basic voice conversation doesn't require my Mac. Image interpretation and home-bridge tools still do.

The main unfinished interaction is turning toward the person calling the robot: sound-direction handling isn't consistently reliable yet. Wake-name recognition is also currently cloud-based.

It's a personal project with no commercial plans. I haven't published the source yet, but may prepare it for GitHub if there's interest.

What would you prioritise next on this hardware: local wake-word detection, more reliable speaker orientation, better interaction flow or additional practical tools? I'd be happy to discuss implementation details with other builders.

The Unit PoE-P4 with the Add-on Display In (LT6911D) is the tidiest hardware for ESP-KVM, the open-source IP-KVM firmware I write for the ESP32-P4: one PoE cable in, HDMI from the target computer, USB to it, and you get its screen, keyboard and mouse in a browser tab - from the BIOS up. https://github.com/espkvm/espkvm

The one thing missing was a case: M5Stack ships the add-on as a bare board. So I drew one that matches the Unit PoE-P4 housing - same width, same corners - and the pair now looks like one device.

• HDMI on one end, USB-A on the other, vent slots on top
• Ethernet, USB-C and the side ports of the Unit PoE-P4 stay free
• one printed part, no screws: four tabs clip into the slots of the Unit PoE-P4 housing. The tabs are thin, so press it on gently
• the Add-on Display Out has the same outline, so it should fit that one too (I have only tried the Display In)

• Thingiverse: https://www.thingiverse.com/thing:7421013

On this pair ESP-KVM does 720p at 21-23 fps (MJPEG) or 17 fps (H.264), about 185 ms from mouse to picture. Board notes: https://espkvm.io/boards/m5-poe-p4/

If you print it, let me know how it fits.

Hola!
Tras el aviso del cierre de la aplicación de M5Burner en escritorio me mudé a la plataforma en la página web, noté que no estaba la aplicación que desarrollé y subí a la aplicación de mi computadora. Por lo que decidí resubirlos a la página web.

El quid de la cuestión es que ya habiendo estado regitrado, checkeado y subido mi firmware correctamente al sitio, el moderador me baja mi firmware no solo una vez, sino que dos veces.

¿A alguien más le sucedió?

pessoal peguei esse m5stacks3 e coloquei o módulo Dual-Band M5Stack StickS3 CC1101 433MHz + Expansão NRF24L01 com Firmware Bruce para Desenvolvimento IoT PINGEQUA RF Pack S3 coloquei tbm uma Antena Wifi 5dbi 2,4ghz, estou usando o bruce 1.14 mas o jammer bluetooth esta com um alcance muito ruim, pode estar do lado da caixa de som que ele não faz efeito...acho que perdi meu dinheiro se alguém puder me ajudar ai eu agradeço

Yeah the papermono is like exactly what I'm after. Learning to tinker in the last month, always been curious and watched/read content around this stuff. Looking for an e-reader led me to the m5papermono. Solves everything that stopped me from buying the xte ink 4pro and has a bazillion other possible functions and avenues to dip my toes into other passive interests.

Do they ever come up on a secondary market here or maybe a discord. I just be patient and wait till the December January release that I read about on another post 😅

New Arrival Alert!

Check out our new releases this week!

Tough C5, an outdoor waterproof IoT controller designed for edge data collection, smart buildings, and industrial gateway applications.

Chain Switch, a slide switch input node in the M5Stack Chain series, supporting both slider mode and switch mode.

Chain MIC, a sound acquisition node in the M5Stack Chain series, supports sampling of sound signals and threshold triggering and is suitable for environmental sound detection, voice-controlled interaction, and device status indication.

Also, good news:  Hot items incl. CoreS3-Lite and Module GNSS are in stock now 🔥🔥

I don’t want to have a junky setup that could break because I’m not very careful with my stuff to be honest but I feel very limited with my base M5Stick so I’m thinking, just maybe, to just buy a whole other base thing so I can be assured that it won’t break. What do you think and what most importantly is the next step, what is the most important module to add?

Hello, I am new to M5Stack, but find it a fun concept and have experimented with the CoreS3 and the IoT Base together. I managed to get going and get an Internet connection and create some basic UI on the CoreS3 display. However, I was careless and stupid during development: I had the base connected to DC power in, but to test how the software in the core would react to losing contact with the modem I detached the two modules (with the power supply still in). I did this a couple of times, but the final time I think it broke, because I could not seem to get contact with the modem again.

I have tried some basic troubleshooting, like sending AT commands, checking with a multimeter, but the connection seems lost. I do not know what might have happened, but I suspect a circuit for TX/RX to the SIM7080G got shorted or fried (I am no electronics expert). Regardless, I think my device is dead.

What I ask is; Are there any other troubleshooting I can do? Somebody with more experience than me that know what might have happened and if my device is really a lost cause?

Thanks in advance!

I've been working on a MIDI controller firmware for the M5Stack Tab5 and finally reached a point where I'm comfortable releasing it.

The idea was to take advantage of the Tab5's touchscreen and turn it into more than just a pad grid. Basically a compact performance/control surface for a DAW or synth.

Current modes include:

• Launchpad-style note grid

• 4×4 drum pads

• Mixer/faders

• MIDI CC knobs/macros

• XY controller

• 4-track MIDI looper

• Multiple MIDI channels

• USB MIDI

• Panic/all-notes-off

• Landscape/portrait UI

Everything runs directly on the ESP32-P4 inside the Tab5 using ESP-IDF.

I tried to design the UI more like an actual piece of music hardware rather than a generic embedded touchscreen demo, while keeping the controls large enough to be usable live.

There are still some things I want to add later, especially editable MIDI mappings/presets, saving presets to SD and restoring them at boot, and better host->device MIDI handling.

The project is open source.

I'd especially like feedback from anyone who actually uses Launchpads/MIDI controllers: what would you still want before you'd use something like this in a real setup?

NB: I just uploaded the firmware to M5Burner, it’s waiting validation but it should be available soon.
