Introduction
The T3-S3 MVSR version is an extended version of the T3-S3 mainboard, featuring a vibration motor, microphone, speaker, and RTC module. Its primary application is for LoRa voice transmission and reception.
This expansion version currently supports two T3-S3 mainboard models: SX1262 and SX1280.
The SX1262 version uses the FSK modulation scheme.
The SX1280 version uses the LoRa modulation scheme.
A corresponding test demo is available on GitHub for development reference. Additionally, this expansion version can be used for AI voice interaction, MP3 playback, and other applications.
