WB9770-00
Ultra-low Power 2.4GHz BLE Wireless Audio Module
WB9770-00
The WB9770-00 module from JORJIN is a wireless audio module targeting at wireless audio streaming for hearables, wireless headsets and headphones applications. This module is based on NXP NXH3670 and KL27.
The NXH3670UK constitutes a highly integrated, single chip ultra-low power 2.4 GHz wireless transceiver with embedded MCU. The NxH3670 runs a proprietary wireless audio streaming protocol which has been optimized for wireless gaming headset applications, providing high-quality forward audio streaming at low latency (<20ms) combined with a simultaneous voice microphone backchannel. Additionally, a wireless bidirectional data channel is available. While primarily designed for headsets, this solution can also enable wireless audio streaming for household and office devices like soundbars, wireless speakers, wireless Subwoofers and more.
