wireless solutions Evaluation Kit wireless solutions EVK2 for all Telit Modules EVK2 with GM862 Interface The Telit Evaluation Kit (EVK2) provides a robust, future-proof and flexible environment for rapid development of applications for the full range of GSM/GPRS, UMTS/HSDPA and CDMA module families, dramatically reducing time-to-market. The kit is comprised of a motherboard, and an adapter board 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. EVK2 with GE863 Interface The motherboard includes the basic interfaces, such as power input, SIM card holder, audio monitor outputs, RS-232, 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 RS-232. Adapter boards are available in different models to allow development for the desired module family (board-to-board or BGA solder). The set of basic interfaces found on by the motherboard. The set of interfaces specific to the module (e.g. antenna, general purpose inputs/outputs (GPIO), 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. The Telit EVK2 is a tool for: EVK2 with GE864 Interface ■ D  eveloping applications based on current and future Telit GSM/GPRS, UMTS/HSDPA, and CDMA module families via AT commands through serial ports ■ P  rogramming and updating of all ■ D  ebugging Telit-module-based applications ■ I mplementing simple applications (stand alone function) by executing scripts using a Python interpreter equipped module without the need fo an external microprocessor Telit modules QUALITY INVESTMENT PROTECTION BUSINESS SCALABLE EASE OF INTEGRATION Making machines talk. ® Evaluation Kit EVK2 for all Telit Modules is in it.

Alternatively, this communication can be done through a CMOS HUB, which ­provides two-way communication compliant to USB 1.1 specifications at higher data rates (up to 1,5 Mbps). The USB connection is ­provided through a USB-A USB-B cable. Serial port selection is made through configuration of jumpers on the motherboard. Power supply inputs The EVK2 is equipped with different power supply inputs enabling its use it in the following environments: ■ A  utomotive setup: 5 to 40 Volt supply ■ L  aboratory setup: + 3.8 Volt fixed supply ■ P  ortable setup: Rechargeable Li-Ion battery pack General purpose inputs / outputs With the EVK2, all general purpose inputs/outputs are made accessible on the adapter boards by a set of pins on the PTH-type connector. This allows developers to build their own interface boards best suited for their requirements, e.g. custom connectors, cables, relays, LEDs, etc. Power supply Automotive setup: 5 to 40 Volt supply Laboratory setup: from + 3.8 Volt fixed supply Portable setup: rechargeable Li-Ion battery pack RESET & power ON button Yes Battery charger control From Telit module OV protection On all input DC lines Reverse polarity protection On all input DC lines LED indicator 2 SIM card holder Yes GPIO Yes (all available on the interface board) Serial ports 2 x RS-232 or 2 x USB 1.1 Mute control Automatic Speaker output 2 output power options: Option 1 - max 10mW / 16Ω on standard 2.5 mm headset socket Option 2 - max 675mW / 8Ω on PTH pin connector Microphone lines 1x Single-ended (INT/EXT) Eearpiece output 1x Single-ended (INT/EXT) max 10mW/16 Ω Order-No. Model EVK2 GM862 Interface GE863-PY Interface GE863-GPS Interface GE864-PY Interface GC864 Interface UC864 Interface CC864-DUAL Interface Copyright © 2008, Telit Communications S.p.A. · Subject to changes in technology, design and availability P/N 3 990 150 463 3 990 250 670 3 990 250 669 3 990 250 671 3 990 250 672 3 990 250 680 - - GSM Engine GE863-PY GE863-GPS GE864-PY [10.2008] RS-232 / USB 1.1 serial ports
