WB9770-00 Image

The WB9770-00 from Jorjin is a 2.4 GHz BLE Wireless Audio Module designed for household and office devices like soundbars, wireless speakers, wireless subwoofers, and headsets applications. The NxH3670 runs a proprietary wireless audio streaming protocol that 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. The device requires a DC supply of 2.7 V.

The WB9770-00 uses MKL27Z256VMP4 as a host controller and communicates with the NxH3670 MCU via an SPI master-slave interface. The host controller also has an I2C master interface which can be connected to the codec or any external I2C device. The device supports BLE GFSK modulation of 1 Mbps and 2 Mbps and is interfaced with a USB full-speed 2.0 device controller which supports the crystal-less operation.

This 2.4 GHz RF module is available with an integrated antenna in a package that measures 19.5 x 12 mm.
