OPENBRAIN Technologies Co., LTD.
1. Summary
This document defines the product specifications of Bluetooth voice communication module (M5G)
including electrical and mechanical characteristics manufactured by OPENBRAIN for customer approval
purposes.
1.1. Product Summary
OPENBRAIN’s M5G is a compact Bluetooth
module designed to provide easy Bluetooth audio
application for communication devices without
Bluetooth functionality. By integrating the module
into communication devices that use
speaker/microphone or wired ear-sets, it enables the
communication device to be used with Bluetooth
headsets within a range of 10m distance.
M5G integrates all the functions needed to
replace existing audio connection wirelessly and has
been designed such that it is possible to control and
monitor the functions externally via serial (UART)
communication thereby enabling Bluetooth
functionality to be implemented into devices in a
short period of time. Also, the module has been designed to be ultra-small and light with minimal power
consumption thereby making it ideal for integration without sacrificing electrical and mechanical design
factors of existing devices. The advantages of using M5G are, it makes production easy and simple as
the modules are RF tuned and tested before supply and it is not necessary for customers to secure
additional Bluetooth test/measuring equipments.
