® Cinterion LGA DevKit Things User Guide Page 4 of 26 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.

If required, you can add simple components (LED, Transistors etc.) here. All module signals, except USB and RF are accessible at the underside by the labeled pads.
® Cinterion LGA DevKit Things User Guide Page 15 of 26 4.11 Power Supply 4.11 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 Things User Guide Page 16 of 26 4.11 Power Supply 4.11.2 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.
