If you're interested in adding voice functionality to your projects, this is the module to buy! The module supports both Chinese and English, and can display current time and environmental data. It can be used alongside a speech recognition module for basic interactive conversations. For connectivity, it offers I2C and UART modes and a gravity interface, providing compatibility with many common controllers. Additionally, it includes a built-in speaker, so there's no need to buy one separately.

Note: the addresses of the speech synthesis module and micro: bit motor driver board are the same, so they cannot be used together.
