T-TWR RF module connect audio to ESP32

[redfast00]

Hi! I'd be really excited to use the T-TWR module for digital HAM radio projects (for example as an APRS modem). Is the RF chip directly connected to the microphone/speaker? Is it possible to send and receive audio waveforms from/to the ESP32?

This would for example also make it possible to build an internet-connected radio repeater

yes.

Newer hardware may support it.
