This compact wireless module supports UHF audio and data transmission. It contains an interface which has an application in which serial communications with an external device allows command control and analog I/O so that MSK modulation can be directly controlled. In another application, the module can be used as a standalone device through the customization of the internal control software.

Also, this module has been designed for use as an embedded device. Unnecessary circuitry and components that were used in earlier mobile wireless devices have been removed. This module, with external dimensions of 97×55×26 mm, now has approximately 40% less volume than the previous JHM-428 series of wireless devices for automobiles.
