1 Introduction
The Cinterion®LGA DevKit is designed as a generic development adapter for Cinterion®LGA
modules. With the LGA DevKit it is no longer necessary to connect the Cinterion®evaluation
modules to an adapter for test and development purposes.
One of the main advantages of the LGA DevKit is that thanks to the interruption possibilities via
jumpers almost all signals can be directly traced or measured without any additional circuits..
The factory default jumper settings start the modules with a minimum of required operational
connections. The benefit of this configuration is the possibilityto use only those signals that are
currently required in the development process.
The LGA DevKit may operate stand-alone without the need of any further tools or devices, or
it can be used as a so called port extender, I.e., an adapter between a module and develop-
ment boards like the DSB75 or the DSB-Mini.
The LGA DevKit is available in two variants:
• SM supports the all industrial platform modules
• L supports most of the industrial plus platform modules
Either one of the LGA DevKit variant (SM or L) needs to be ordered together with the LGA
DevKit Socket, leaving the option to reuse the Socket for the other LGA DevKit variant.
1.1 Feature and Benefits
• LGA DevKit Socket supports four different module footprints for industrial/industrial plus
modules:
With LGA DevKit SM: LGA106, LGA114, and LGA120
With LGA DevKit L: LGA156
• Future proof, ready for new, upcoming modules
• Improves the module inter-compatibility
• Stand-alone: Get the LGA module up and running without any additional tools or devices
• Supports DSB75/DSB-Mini as port extender
• UART via USB VCP, and/or native USB communication
• Direct module signal access with complete interrupt for deep level investigation
• Real module current consumption measurement, no additional leakage current
• Powered via USB or external devices (e.g., DSB75/DSB-Mini)
• Adjustable module supply level between 2.8...4.5V
• VEXT self-adjustment for level shifter reference level
• Interfaces also supported: SPS, SIM2, ASC1, Audio, GPIO, GNSS
• Error detection: Wrong or wrongly oriented modules, as well as module shorts preventing
damages to LGA DevKit, LGA DevKit Socket and/or modules
• Clear & easy concept for usage and signaling
• Cost minimized: LGA DevKit Socket usable for both LGA DevKit versions (SM and L)
• QR code scanning leads users to all the information necessary for usage

2 Quickstart
Please complete the following steps to quickly get started with your LGA DevKit.
• Mount the LGA DevKit Socket onto the LGA DevKit (for details see Section 2.1).
• Insert the fixing frame and then the module into the Socket and close the retention lid by
pressing it down and turning it clockwise.
• Connect the provided antenna to the SMA connector named "MAIN".
• Check that the jumpers are set to their default delivery positions.
• Connect your host PC to either the USB or the USB VCP connector (depending on the mod-
ule). In case of USB VCP connections, install FT232R drivers.
• Set the switches PWR & ASC0 at the DevKit's lower right corner to "USB". Now, the green
"PWR" LED lights up.
• Shortly press the ON button to start the module. Now, the white "ON" LED lights up
The red "ERROR" LED may indicate issues that should be corrected. For de-
tails see Section 4.9.
Note: By scanning the QR code at the back of the LGA DevKit you will also find
further information, videos and available drivers.
2.1 Mounting the LGA DevKit Socket
Before operating, the socket has to be mounted onto the LGA DevKit
with 4 screws. Scanning the QR code on the DevKit's back and/or the
quick start guide will lead you to the DevKit's web home where you find
a short introduction and video on how to do this.
The white printing on the DevKit shows how the socket shall be orien-
tated and mounted. You can quickly adapt to different module foot-
prints by using dedicated fixing frames. All contacts have low-
resistivity needles that can withstand a permanent DC current up to
1.7A per needle.
Note: The module's thermal encapsulation inside the Socket increases the thermal resistance
(Rth). Thus, you need to be aware that the board temperature may rise quite quickly until au-
tomatic thermal shutdown takes effect, especially at higher environmental temperatures or high
radio output power.

Page 9 of 28
4 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).
Figure 4: SIM settings

Cinterion® LGA DevKit User Guide
4.3 Pin Headers
27
lga_devkit_ug_v02 2019-05-27
Preliminary
Page 10 of 28
4.3 Pin Headers
The pin headers at the head of the LGA DevKit's top side can be used to setup connections
between modules and possible on board peripherals. Thus, pin headers having signal names
at their left side only, namely the pin headers AUDIO, CONTROL, ASC0_A, ASC0_B, DAI,
ASC1, GPIO, and PWR, can be bridged by jumpers. All of these pin headers have the module's
signal name on their left side (orange box in Figure 5), whereas the right side corresponds to
peripherals like level shifters or the DSB connector (green box in Figure 5).
• Placing a jumper connects a line through a level shifter to the associated pin at the 2x40 pin
connector at the bottom of the LGADevKit (and thus toa connected DSB75/DSB-Mini). See
also Figure 3.
• Not placing a jumper leaves a module signal line open.
External periphery can also be connected to all accessible module signals directly. When con-
necting other external periphery to the pin headers pay attention not to violate the maximum
module ratings.

4.4 ON Button: Module Start and Power Down
27
lga_devkit_ug_v02 2019-05-27
Preliminary
Page 11 of 28
4.4 ON Button: Module Start and Power Down
Pushing the ON button shortly (i.e., <0.5s), the LGA DevKit starts up and initially analyses the
mounted module orientation and type. In case both are recognized and correct, the module is
started using specific start pulses. The white LED indicates the modules VEXT state as high.
Picture TBD.
Also, it is possible to start up the module by toggling DTR on the DSB75/DSB-Mini RS232 con-
nector.
Pushing the ON button for more than 2s shuts down the LGA DevKit's power supply, and the
module's power supply is interrupted regardless of its current state.
4.5 RST Button: Module Reset
Pushing the RST button pulls down a module's EMERG-RST/OFF signal, thus forcing it into
reset or off state depending on the module. Please note that this functionality is only available
if the (default) jumper is set for EMERG_RST at the CONTROL pin headers (see Section 4.3).
4.6 ASC0 Switch: Module UART Interface Selection
The "ASC0" switch selects the module's UART communication interface either via USB VCP
(FTDI232R) or via "RS232" D-Sub interface on the DSB75/DSB-Mini.
Changing this from "USB" to "RS232" during operation resets the FTDI VCP bridge in order to
release the signal lines, thus leading to a USB VCP disconnect on the host PC side.
4.7 PWR Switch: Power Source Selection
The "PWR" switch selects the preferred power source, both sources can be connected at the
same time, but do not supply the LGA DevKit in parallel.
When "USB" is set, both LGA DevKit USB ports will contribute to the overall power supply with
a connected DSB75/DSB-Mini having to be powered separately. Setting "EXT", the power is
supplied from the DSB75/DSB-Mini interface.
Please note that there is a dedicated power supply for the GPS antenna. To use this, the two
pins at the GPS_PWR field will have to be soldered and connected by jumper.

Page 12 of 28
4.8 Free Level Shifters
The LGA DevKit provides 8 free level shifters, with 4 placed & connected at the patch field on
the bottom side, and 4 connected to the pin header "LEVELSHIFTER". The level shifters on
the pin header are referenced to the module's Vext, and Vref that by default corresponds to 3V
or to "REF IN" if connected (see Section 4.12.2).
These level shifters can be used to level shift signals that are not available at the DSB connec-
tor.
4.9 LEDs
4.10 Patch Field
A small patch field is available at the LGA DevKit's bottom
side. If required, you can add simple components (LED,
Transistors etc.) here. All module signals, except USB and
RF are accessible at the bottom through the labeled pads.
4 level shifters are accessible close to the patch field as
well with the reference Vext and Vref. The Vref related lev-
el shifter connections can also be accessed via four addi-
tional pads at the left bottom side of the LGA DevKit where
additional pins may be soldered.
Attention: You will lose your warranty if the patch field was
soldered/used.

4.12 Power Supply
27
lga_devkit_ug_v02 2019-05-27
Preliminary
Page 14 of 28
4.12 Power Supply
The LGA DevKit can be supplied through one or two USB ports that should be in the range of
5V +-5%, and/or externally by theDSB75/DSB-Mini. The modules supply level can be adjusted
in the range between 2.8…4.8V by setting the variable resistor at the DevKit's top side. The
DevKit power supply path is short protected with ~2A. In case of overcurrent the power path
will be interrupted and the red LED lights up until the power has been reset.
As a recommendation the LGA DevKit should be supplied with 5V/1A over one or two USB
ports. The onboard bypass capacitors should buffer enough energy to support short 2G peak
currents up to 2.5A.
4.12.1 Supply Current Measurement
The LGA DevKit supports three methods to measure the current consumption of the inserted
module.
• Measure the voltage across the on board 100 mOhm shunt resistor.
• Measure the current by a current meter.
• Power the module by an external power supply e.g. power analyzer.
All options require a jumper placed on the 4th "BB" and 5th "RF" row for connecting baseband
and radio. Those two jumpers also allow to measure the current separately for the BB and RF
path.

4.12.2 External Reference Supply
To drive/operate the LGA DevKit's interfaces at certain voltage levels, an external reference
voltage may be connected. By default, i.e., without an external reference voltage connected,
the interface operates at 3V to meet the DSB75/DSB-Mini requirements. But if it is required to
operate the interface at another voltage, an external source in therange between 1.2V...5V can
be connected to "REF IN" and "GND" as shown in Figure 11.

Page 17 of 28
6 Operating DevKit on DSB75 and DSB-Mini
The LGA DevKit supports a 2x40pin connector at its bottom side, compatible to the DSB75/
DSB-Mini. A DSB may be a port extender for an RS232 interface, a second SIM or an analog
audio interface. When operating the LGA DevKit with a DSB the following settings can be ad-
justed.
• Use the "PWR" switch to select the power source. If you select "EXT", the DevKit expects
the power on the DSB connector. If you select "USB", the DevKit is powered by its USB
ports, and the DSB expects a separated power source.
• Use the "ASC0" switch to select the first UART. If you select "RS232", the modules ASC0
is conducted to the DSB and can be accessed on the D-SUB connector. If you select "USB"
the UART can be accessed via USB VCP port
Note that the USB VCP bridge will be in reset state while "RS232" is activated. As a conse-
quence the interface is de-enumerated on host side.
Please refer to Section 10.3 for a DSB-Mini patch needed to operate ASC0 on DSB-Mini
