EH-MA46 is a class I Bluetooth® 2.1+EDR (Enhanced Data Rates) module. It is a highly integrated and sophisticated module which contains all the necessary elements from radio to antenna and a fully implemented protocol stack. It is an ideal solution for integrating Bluetooth® into various products with limited knowledge of Bluetooth® and RF technologies.

 With Ehware's AT command stack firmware, designers can easily customize their applications to support different Bluetooth profiles, such as SPP, HID and iAP etc.
