3.7.1. RESET_N Signal

The RESET_N signal can be used to force a hardware reset on the card. Customers can reset the
module by driving the RESET_N to a low level voltage with the time frame of TBD1~TBD2ms and then
releasing it. The reset scenario is illustrated in the following figure.

3.7.2. WWAN_LED_N Signal

The WWAN_LED_N signal of EP06 module is used to indicate the network status of the module, which
can absorb the current up to 40mA. According to the following circuit, in order to reduce the current of the
LED, a resistor must be placed in series with the LED. The LED is emitting light when the WWAN_LED_N
output signal is active low.
