-Works with [ESP32-A1S](https://docs.ai-thinker.com/esp32-a1s) module that includes audio codec and headset output. You still need to use a demo board like [this](https://www.aliexpress.com/item/4001060963585.html) or an external amplifier if you want direct speaker connection.

This is a fun [smartwatch](http://www.lilygo.cn/prod_view.aspx?TypeId=50036&Id=1290&FId=t3:50036:3) based on ESP32. It has a 240x240 ST7789 screen and onboard audio. Not very useful to listen to anything but it works. This is an example of a device that requires an I2C set of commands for its dac (see below). There is a build-option if you decide to rebuild everything by yourself, otherwise the I2S default option works with the following parameters
