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 possibility to 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.

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
