Dimensions
• Product Information
* Power Supply Specification
The power of DC3.1V ~ 3.6V is should be supplied to the Bluetooth module power(VDD). The module supplies the
power to the each block depending on the function. Module input power in excess of the rated input power may cause
damage to the internal components. And the influx of Surge and ESD also may lead to the damage of the modem in
the vehicle. For the prevention of this, the module is necessary to design block the influx of Surge and ESD.

(Module case) MIN TYP MAX
11 VDD_3V3 In 3.1V 3.3V 3.6V
* RESET
The RESETB pin is an active low reset and is internally filtered using the internal low frequency clock oscillator. A
reset in performed between 1.5 and 4.0ms following RESETB being active. LGIT recommends that RESETB be
applied for a period greater than 5ms between the falling and the rising threshold voltage.
