The Telit Evaluation Kit (EVK2) provides a robust, future-proof and flexible environment to streamline all application development based on Telit GSM/GPRS, UMTS/HSPA, CDMA 1x/EV-DO, and LTE module families, significantly reducing time-to-market. The kit includes a motherboard and an adapter board where the target 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 such as power input, SIM card holder, audio monitor outputs, RS-232, and USB; as well as a Reset button and power switch. The circuit implemented in the EVK2 motherboard is based on the recommended reference design for the module's peripheral components and I/O connections. Jumper blocks on the motherboard define the routing of the serial interfaces, audio signals, and power supply. The AT-command interface to control the module can be PC or DTE type and connected via the USB or RS-232 ports.
Adapter boards are available for all the different module families. Adapter boards for modules with board-to-board connectors may be used for development with a number of different target modules sharing the same form factor. The desired target module in this case must be specified and ordered along with the EVK and adapter board. SMT (BGA, LGA, etc.) modules on the other hand come pre-mounted (soldered) on the adapter board.
In addition to the basic interfaces included in the motherboard, the adapter board provides the set of interfaces specific to the target module (e.g antenna, GPIOs, ADC/DAC, UART, etc.). The two combined make up the complete set of connections available for the user application, extension boards, or other development tools and measuring equipment.
