3990150502

3990150474 is a evaluation kit that provides a flexible environment for development of GSM/GPRS applications. The motherboard has a module interface connector in which the relevant module is connected. This concept allows the EVK2 to be used across various form factors and product generations, both present and future. The motherboard includes the basic interfaces. The motherboard represents the recommended reference design for the module's peripheral circuitry. Jumper blocks on the motherboard define the routing of the serial interfaces, audio signals, and power supply. The PC or DTE controlling the module over the AT command interface can be connected via USB or RS232. Adapter boards are available in different models to allow development for the desired module. The set of interfaces specific to the module is found on the adapter board for connection to the user's application, extension boards, or other development tools and measuring equipment.
