9.1.2 EVB for camera support
In order to interface the Telit GM862-GPS with a CMOS camera, Telit has developed an evaluation
board. The EVB is provided by:
• 10 pin Berg male connector (PL201) and RS232 level translator that allows a direct connection to
the PC. To switch on the level translator a jumper shall be set on PL203.
• 12 pin Berg male connector (PL202) to supply the GM862-GPS mounted on the EVB. The input
source power should be in the range 4,5V-12V. Charge line is also provided in case a Li-Ion
battery is connected to the VBATT pins. Charge input must fulfil charger line requests.
• 50 pin Molex male connector (PL103) to interface with the GM862-GPS directly.
• 30 pin Berg male connector (PL101) to interface with a PCB developed by the user or the EVK
board. On this connector is available the complete audio path, the serial port lines with full
handshaking, and the pins ON, AXE, RESET, GPIO1 and STAT_LED. Also the CHARGER_IN pin
can be available placing a 0 ohm resistor.
• 18 pin ZIF female connector (SO101) for CMOS camera.
• ON/OFF button (SW102) to power on and off the module.
• GPIO1 button (SW101) for future applications.
• Led (DL101) for device status indication.
NOTE: The Philips 74LVC1G08GW must be placed close to the GM862 connector; the length of the line between
CAMERA connector and MOLEX 50 PIN of GM862 must be max 5cm anyway.
NOTE: The CMOS cameras must be removed when the GPIO pins are used for I/O purpose.
