Muse Proto Radio project 📻

This is an how to guide for the Muse Proto board to implement a simple internet radio project with this board. The beauty of this product is that in includes a built in speaker, microphone, and the ability to add a battery.
it could be purchased here :

At the end of this tutorial you will be able to :

  • Listen to an internet radio of your choice
  • Change stations
  • Change volume
  • Use a web interface to chang wifi credentials, or station presets

First thing first turn ON the board, pull he switch toward the USB port

1. Download files
All files with the last version are here:
Download the archive :

unzip the files.

2. Copy then library
In the unziped archive copy the directory muse_lib in your arduino library folder, on windows this is in Documents\Arduino\libraries , if you are on linux /Arduino/libraries

3. Install the ESP32 board in the Arduino IDE (skip this step if you already installed it)

A. In your Arduino IDE, go to File > Preferences

Installing ESP32 Add-on in Arduino IDE Windows, Mac OS X, Linux open preferences

B. Enter into the “Additional Board Manager URLs” field as shown in the figure below. Then, click the “OK” button:

Note: if you already have the ESP8266 boards URL, you can separate the URLs with a comma as follows:,

C. Open the Boards Manager. Go to Tools > Board > Boards Manager…

D. Search for ESP32 and press install button for the “ ESP32 by Espressif Systems “:

E. That’s it. It should be installed after a few seconds.

Complete instructions are here :

4. Target option in Arduino IDE Tools

  • Select the following options in the arduino IDE:


  • Plug the Muse proto board and set the right com port in the menu showed above.

  • Upload files such as wave file and config files to the ESP32 flash memory usuing the ESP32 Sketch Data Upload (see picture above), this is using Flash File System (SPIFFS) you can find more info here if you would like to go deeper on the subject (optional):

  • Upload the program to the ESP32 : image

4. Set wifi credentials and internet stations
If the radio found no internet connexion it will start a wifi access point called “muse”, connect to it to it using password : “musemuse”

Once connected in a browser go to

you should have this screen with the list of radios and at the bottom a link to set wifi credentials:

You will access to that page:

  • Thing name is the ssid that will be displayed if no internet connexion is found (AP mode)
  • AP mode password
  • The SSID name of your home wifi
  • The password of your wifi
  • add station
  • new name of the radio preset
  • URL of this radio
    Once set click on Apply

reset and you should after a few second hear the 1rst radio on the list.

4. Buttons and screen

Tho have the full experience you can add 3 buttons:

  • VM (gpio 32)
    • short press => volume -
    • long press => previous radio
  • VP (gpio 19)
    • short press => volume +
    • long press => next radio
  • MU (gpio 12)
    • short press => mute/unmute
    • very long press => stop (deep sleep) / restart

(optional) And a little screen (64x128 SH1106) (sda gpio 18, scl gpio 15)

Here is the result:
