® Cinterion LGA DevKit User Guide Page 5 of 36 1 Introduction Introduction ® ® The Cinterion LGA DevKit is designed as a generic development adapter for Cinterion ® modules. With the LGA DevKit it is no longer necessary to connect the Cinterion evaluation modules to an adapter for test and development purposes.

® Cinterion LGA DevKit User Guide Page 12 of 36 4 LGA DevKit Interfaces LGA DevKit Interfaces 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.
® Cinterion LGA DevKit User Guide Page 13 of 36 4.3 Pin Headers Pin Headers The pin headers at the top side can be used to setup connections between modules and pos- sible on board peripherals. Thus, pin headers having signal names at their left side only, name- ly the pin headers AUDIO, CONTROL, ASC0_A, ASC0_B, DAI, ASC1, GPIO, and PWR, can be bridged by jumpers.

® Cinterion LGA DevKit User Guide Page 16 of 36 4.11 RF Antenna 4.11 RF Antenna The LGA DevKit supports three antenna interfaces. The two SMA connectors "MAIN" and "DRX" are used for radio transmission. The GNSS interface is supported by an U.FL connector named "GPS".
® Cinterion LGA DevKit User Guide Page 17 of 36 4.12 Power Supply 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 the DSB75/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.
® Cinterion LGA DevKit User Guide Page 18 of 36 4.12 Power Supply 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.
