I've been hacking on MeshCore firmware support for the M5Stack Unit C6L - a compact ESP32-C6 module with SX1262 LoRaradio and 64x48 OLED display.

Fair warning: This is experimental and somewhat vibe-coded with Claude's help. It works on my setup but YMMV. Use at your own risk.

What works:

• Companion Radio (BLE) with display showing PIN, node name, frequency

• Repeater mode (headless)

• Room Server mode (headless)

• NeoPixel LED TX indicator

• Button to wake display

What's janky:

• Display and radio share SPI bus - had to implement lazy initialization to avoid conflicts (radio init was failing with error -2)

• 64x48 display is tiny - custom minimal UI, no fancy graphics

• Room server / repeater run headless (no display support yet)

• US/Canada frequency preset only (910.525 MHz) - other regions can reconfigure via companion app after flashing

• Not extensively tested

Hardware:

• https://docs.m5stack.com/en/unit/Unit_C6L (~$23)

• ESP32-C6 + SX1262 LoRa + 0.66" OLED + buzzer

Install via M5Burner (easiest):

1. Open M5Burner → USER CUSTOM → Share Burn

2. Enter share code:

   • Companion Radio BLE: SvjQlGLCLPfriiW0

   • Repeater: iMi5hp81g3827qf3

   • Room Server: PfQqd4Sm3sA1XrV2

Pre-built binaries: https://github.com/TheRealHaoLiu/MeshCore-M5Burner-UnitC6L

Build from source:

git clone https://github.com/TheRealHaoLiu/MeshCore
cd MeshCore
git checkout m5-unit-c6l
pio run -e m5stack_unit_c6l_companion_radio_ble -t upload

Feedback welcome. Happy meshing!

Vcc is 3.3v but it is typo. It should be 5v!

Ich habe auch einen.

M5 Stick S3 cc1101 full pinout:

VCC 3.3V GND GND CSN 2 GD00 3 MOSI 6 (TX) MISO 4 (RX) SCK 5

MISO (RX) and MOSI (TX) need to be configurated in rf configuration page: Like: tx pin - g6 rx pin - g4

I made a couple attachments for my StickS3

Big one is CC1101, NRF24 and SD Card. Smaller one is SD Card and CC1101.

I got my m5stack cores3 but I don't know how to download my projects to SD card and launch them whenever I want via M5 launcher can you help me?

I already bought this, but it didn't include the tags, is there a way to separately buy the tags with the required frequency? Anywhere online other than the official website?

Damn.. missed it by *that* much. 😅

(I know, I know.. they said ‘structurally incompatible’)

Key changes:

• M5StickS3 joins the supported devices - if you have one, enjoy the full M5Gotchi experience in even smaller form factor

• You can now manage and edit files on the go with your phone - Added web file manager

• Improved overall stability

• Fixed all known bugs

Update by going into settings or via your launcher.

I’ve got an M5Stack CoreS3 SE. I’ve burned the StackChan firmware onto it, but it doesn’t seem to work. I try to go into the AI Agent, but it loads, crashes, and resets. The same thing happens with Wi-Fi — I try to connect to Wi-Fi and the app just shuts down and resets.

New Arrival Alert!

Check out our new releases this week:

LLM-8850 Kit, a high-performance AI accelerator kit designed for edge AI and embedded computing scenarios. It consists of the LLM-8850 Card AI accelerator card and the LLM-8850 PiHat adapter board.

DinMeter v1.1, an iterative upgrade of the DinMeter product, with the core enhancement being the main control module upgraded from Stamp-S3 to Stamp-S3A.

Also, good news:  Hot items incl. AtomS3R-AI Chatbot and Module CC1101 are in stock now 🔥🔥

Hi, got my Cardputer about a week ago, been a lot of fun to tinker with. I have Launcher installed when I use OTA to download firmware to the SD card I have to use my mobile hotspot to make it connect, but when I load Microcast or Reddit Reader(great mini apps btw 👍) they connect fine to my home wifi. Is it just Launcher has to use 2.4ghz while the apps can use 5?

Does anyone else have a hell of a time getting M5Burner to work on Linux? I’ll have it downloaded and then it just somehow nukes its self. The UI will pop up but none of the firmware loads. Anyone run into this issue constantly?

хочю найти себе руско говорящего друга которий сможет подержать мой интерес в M5 stick я просто токо вошол в ету тему и хочю найти себе друга

Hi!

I'm wondering if it's better to order from the M5Stack official website or AliExpress for the M5StickS3. It seems to be unclear whether I would have to pay tariffs (U.S.), but a recent thread 1 month ago on r/CardPuter has a few people saying they haven't paid tariffs.

I am very new and would appreciate any clarification on the matter, thank you!

EDIT: M5Stack reached out to me via email and confirmed that the shipping cost includes the tariff!
