Bluetooth Audio Module
BTM98-8AA
The RESET pin is an active low reset and is internally filtered using the internal low frequency
clock oscillator. A reset will be performed between 1.5 and 4.0ms following RESET being active. It
is recommended that RESET be applied for a period greater than 5ms.BTM98-8AA has an internal
reset circuitry ,when BTM98-8AA input 5V charging voltage, Module reset once.
The capacitor discharges through 220 k resistor, which eventually deactivates the reset.
Time constant of the RC circuitry is set in a way that the supply voltage is safely stabilized before
the reset deactivates.
