® Cinterion LGA DevKit User Guide Page 5 of 28 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 6 of 28 2 Quickstart 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).

® Cinterion LGA DevKit User Guide Page 9 of 28 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 10 of 28 4.3 Pin Headers 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.

® Cinterion LGA DevKit User Guide Page 12 of 28 4.8 Free Level Shifters 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"...
® Cinterion LGA DevKit User Guide Page 13 of 28 4.11 RF Antenna 4.11 RF Antenna The LGA DevKit supports three antenna interfaces. The two SMA connectors "MAIN" and "DRX" can used for radio transmission. The GNSS interface is supported by an U.FL connector named "GPS".
® Cinterion LGA DevKit User Guide Page 14 of 28 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 15 of 28 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.

® Cinterion LGA DevKit User Guide Page 17 of 28 6 Operating DevKit on DSB75 and DSB-Mini 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.
® Cinterion LGA DevKit User Guide Page 18 of 28 7 Module Specific Configuration Settings Module Specific Configuration Settings BGS2 Operation BGS2 requires a reference voltage for the I/O domain at VDIG (pad 10 of the LGA106 foot- print). Therefore please connect IO25 and VEXT via a jumper. EHS5/6/8 Operation Some early samples of EHS5/6/8 require the AUTO_ON circuit.
