Great controller. It will have a lot of applications in different projects. Most esp32 applications will be able to be used without customization.

Thanks for the video. Could you disclose how to use RS232 with Home Assistant? Which GPIOs or PINs are used for TX and RX in A4? How to make good config for this?
