This project is based of pschatzmann/arduino-snapclient and prior work of others.
- wifi network loudspeaker which receives data from a Snapcast server
- ESP32 use ethernet instead of WiFi (WT32-eth01)
- interface with low power I2S amplifier (MAX98357A)
- OTA via ethernet (only possible shortly after boot)
- interface with high power I2S amplifier (TAS5713)
- synchronize with other speakers
- create PCB to amp-board powering everything from one power supply 12-20V
- RP2040 use ethernet (W5500-EVB-PICO, RP2040-ETH Mini)
- allow OTA at all times (see RTOS example)
