The HannaBox is a Wifi enabled music player for toddlers and small children. It features an sd card reader, three buttons, a speaker up to 3 watts and an RFID reader. It is powered by a ESP32 microcontroller module.
## Preparation
The library https://github.com/schreibfaul1/ESP32-audioI2S is not available for Platformio in a working version. It is linked into the `lib` folder as a git submodule.
Init and pull the submodule before continuing:
```
git submodule update --init
```
## Microcontroller
We are using an ESP-WROOM-32 module. For the mp3 decoding we need a multicore CPU, be careful, there are some ESP32 with only one core.
