Status
Indicators
D0310, D0311,
D0312, D0313,
D0201, D0202,
D0203, D0204,
 D0310: VBAT ON/OFF indicator
 D0311: power ON/OFF status indicator for
LTE-QuecOpen modules
 D0312: network status indicator for LTE-QuecOpen
modules
 D0313: power saving mode status indicator for
BG96-QuecOpen module
 D0201~D0204: used for GPIO testing, and a high level
will light up the LEDs
TE-A Interfaces
J0101, J0102
Connectors for LTE-QuecOpen TE-A
J0804
Connector for codec board interface
J1001, J1002
Connectors for of Wi-Fi & Ethernet TE-A
ADC Interfaces
J0403, J0404,
J0405
 Insert the jumper cap: connect the analog signals on
EVB to the module’s ADC interface
 Pull out the jumper cap: external analog signals can be
connected to the connectors’ upper pins
GPIO Interfaces
J0201, J0202
The GPIO pins can be short-circuited to other functional pins
via the jumper caps.
