LGA DevKit Interfaces

4.1

USB

The LGA DevKit comes with two USB interfaces supporting power supply and serial commu-
nication. You may choose to setup communication via a module's USB port and/or a module's
UART (ASC0) port via FTDI232R VCP.

Both USB ports can be used in parallel while power is sourced from both ports.

The native USB power is isolated from the VCP USB power by a diode, meaning that the
VCP USB power does not feedback to the native USB power, but vice versa. This should
be taken into account when supplying the LGA DevKit from different USB power sources,
depending on the voltage levels there could be a power feedback from native USB to VCP
USB.

In case of marginal USB power supply both USB ports should be used to improve power
capabilities.

Note:

 The modem's USB driver can be downloaded from the LGA DevKit's web page that can

be reached by scanning the QR code.

4.2

SIM

On the LGA DevKit's bottom side you find a SIM card holder that is
connected to the module's regular SIM interface lines, except for the
CCIN line where the (default) jumper needs to be set for CCIN at the
CONTROL pin headers (see 

Section 4.3

). However, some modules

come with an additional SIM interface. This can be accessed in con-
junction with a DSB75/DSB-Mini (as port extender) to support dual
SIMs - with the DSB75/DSB-Mini serving as the second SIM interface. 

Some Cinterion

®

 modules require additional components at the SIM

interface, for instance pull-up resistors managed by the DevKit's con-
trol logic. These can be overridden by setting a switch on the DevKit's
bottom side - see 

Figure 4

. For modules requiring a CCIO pull up re-

sistor this switch should be set to "CCIO PULLUP" (see 

Section 7.3

).
