For more information on the characteristics of the SIM card interface, please refer to
the module's hardware guide.

3.3.7 Micro SD Card Interface

The DVK provides a micro SD card interface. Customers can insert a micro SD card
into the socket as memory function. Before using this function, please refer to
module's hardware guide and make sure the module supports SDIO interface.

3.3.8 Antenna Interface

The DVK provides three antenna connectors: MAIN and AUX SMA RF connectors
and GPS coaxial antenna connector. The external antennas should be assembled
well before powering on the module.
SMA antenna connectors can be connected to an RF tester (CMU200 or Agilent
8960), or directly connected to external antennas for the testing services of the
existing network. The GPS coaxial antenna connector can be directly connected to
external GPS antenna for the test of GPS performance.

3.3.9 UART Interface

The DVK provides one 4-line UART interface (UART 1), one 8-line or 4-line UART
interface (UART 0) and one 2-line UART interface (UART 2).

3.3.10 DIP Switch SW601

The interface board provides DIP switch SW601.

When the VBAT signal is toggled to "ON" side, it
kΩ resistor. Please keep VBAT in "ON" state anytime to discharge
through a 10
voltage when the module powers off.
When the POWER_ON_OFF signal is toggled to "ON" side, it is pulled down to
GND. In this situation, once the module is supplied power, it will be powered on
automatically. Note that this function works only when R645 is mounted.
