Internet radio with the ESP32
Many radio stations can be listened to as MP3 streams via the Internet. Since the ESP32 microcontroller has WLAN capabilities on the one hand and can convert the digital data stream into an analog signal with two built-in digital/analog converters on the other, it is the ideal solution for this project. In addition, an MT3608 power supply unit and a TP4056 charge controller for the battery power supply, an audio amplifier, two loudspeakers, a display for the transmitter display and an input device for the transmitter setting (KY-040 rotary encoder) are offered in the bundle. You can round off the project with a housing from the 3D printer.
The following project products are included in the bundle:
- ESP32 NodeMCU Module WLAN WiFi Development Board
- PAM8403 digital mini audio amplifier
- TP4056 Mini USB 5V 1A Charge Controller Lithium Li
- MT3608 DC-DC power supply adapter step up module
- HD44780 1602 LCD module display bundle with adapter
- KY-040 Rotary encoder Rotary encoder module
- Perforated grid board
- 2 DFplayer Mini 3 Watt mini loudspeakers
These products are additionally required depending on the implementation:
- EEMB 3.7V 2000mAh Lipo battery
- Resistors Resistor Kit 525 pieces
- electrolytic capacitor 1000uF / 10V
- Female connectors 19-pole
- Pin header 3-pole
- Male connector 4-pole
- Male connector 5-pole
- Rotary knobs for 6mm axis
- Jumper cable female to female
-
