1. M5stack Core2
2. M5Stack Core2 I2C Port Plug with Wire
3. SD Card 2GD
4. RDA5807M
5. USB Cable Type C

Alright, first things first — make sure your M5Stack Core2 is powered off. No sparks today!

Now grab your RDA5807M FM radio receiver. Time to give it some legs — solder the header pins neatly onto the module.

Next, take your jumper wires and connect it up like this:

1. VCC → VCC on the Core2 I2C port
2. GND (black wire) → GND
3. SDA → SDA
4. SCL → SCL

Once that’s done, gently plug the connector into the I2C port of your M5Stack Core2. It should fit snugly.

Perfect! Now stick or glue the RDA5807M module to the back of the Core2 — nice and secure.

Add the M5Stack Board URL:

1. Go to File > Preferences (or Arduino IDE > Preferences on macOS).
2. In the “Additional Boards Manager URLs” field, add:
3. text
4. 
   

https://raw.githubusercontent.com/espressif/arduino-esp32/master/package_esp32_index.json

1. Click OK.
2. Install the M5Stack Board:
3. Go to Tools > Board > Boards Manager.
4. Search for “M5Stack”. You’ll see “M5Stack by M5Stack Official”.
5. Click Install to add support for the M5Stack Core2 and other M5Stack boards.
6. Once installed, go to Tools > Board > M5Stack Arduino and select M5Stack-Core2.

Install the Required Libraries

1. RDA5807.h
2. Radio
3. Webradio
4. M5unifid.h

Download and Upload the Code

1. Grab the Code: Copy the code I provided earlier (the one for the All-In-One Pocket Tool). I’ll tweak it below to make the UI a bit more customizable and add the thermometer and compass explicitly.
2. Paste the Code: Open a new sketch in the Arduino IDE and paste the modified code (below).
3. Select the Board and Port:
4. Go to Tools > Board > M5Stack Arduino > M5Stack-Core2.
5. Connect your M5Stack Core2 via USB-C to your computer.
6. Go to Tools > Port and select the port your M5Stack is connected to (e.g., COM3 on Windows or /dev/ttyUSB0 on Linux/macOS).
7. Upload the Code: Click the Upload button (right arrow) in the Arduino IDE. Wait for it to compile and upload. You’ll see “Done uploading” when it’s ready.

Now Your tiny smallest portable FM-AirPod is ready to enjoy

Tune the FM radio And Enjoy
