Telit's Evaluation Kit EVK2 provides a flexible environment for the development of applications for the full range of GSM/GPRS, UMTS/HSDPA and CDMA module families, helping customers to reduce time-to-market of end products.
The kit comprises a motherboard and an adapter board in which the relevant module is inserted. 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 such as power input, SIM card holder, audio monitor outputs, RS232 and USB 1.1, as well as a reset button and power switch. 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 family (board-to-board or BGA solder). The set of interfaces specific to the module (eg, antenna, general purpose inputs/outputs, ADC/DAC, UART etc) is found on the adapter board for connection to the user's application, extension boards or other development tools and measuring equipment.
