High integration - speech + Wi-Fi + BLE All-in-One
The chip integrates built-in Wi-Fi and BLE connectivity, with simplified peripherals requiring only one crystal oscillator and a few resistors and capacitors to develop various online&offline or IoT solutions.
Strong control capability
More abundant IO interfaces, compatible with 3.3V and 5V; high clock frequency (240MHz), larger SRAM, providing ample computing power for the main control applications.
Compatibility with multiple IoT platforms
Currently supports Tuya IoT, Tencent IoT, Alibaba IoT (under development), and can simultaneously connect to multiple IoT platforms. CI2306 also has offline&online speech recognition capabilities.
Powerful natural language interaction capability
Strong noise resistance: 85% recognition rate and 90% wake-up rate under 85dB noise (noise reduction mode). Supports up to 300 command words, and some support on-device NLP.
