v 2. Soldering the headers Before using your click™ board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 GSM click™ 2 3 1. Introduction 4. Essential features GSM click™ with it’s Telit GL865-QUAD IC is ideal for mobile devices. It features GSM/GPRS protocol stack 3GPP (release 4 compliant) and supports GSM/GPRS 850/900/1800/ 1900 MHz Quad-band frequency. Additional features Turn the board upside down so that Turn the board upward again. Make sure such as integrated TCP/IP protocol stack bottom side is facing you upwards. Place to align the headers so that they are (including UDP, SMTP, ICMP and FTP), serial shorter parts of the header pins in both perpendicular to the board, then solder the multiplexer, remote AT commands and many soldering pad locations. pins carefully. more, extend the functionality of the board. GSM click™ is an add-on board in mikroBUS™ form factor. It’s a compact and easy solution 3. Plugging the board in click™ for adding GSM/GPRS mobile phones standard to your design. It features a GL865-QUAD Once you have soldered the headers your GSM/GPRS module, a TXB0106 6-bit board is ready to be placed into desired BOARD bidirectional voltage-level translator and a mikroBUS™ socket. Make sure to align the www.mikroe.com SIM CARD socket. GSM click™ communicates cut in the lower-right part of the board with the target board microcontroller via with the markings on the silkscreen at seven mikroBUS™ lines (RX, TX, INT, PWM, the mikroBUS™ socket. If all of the pins are GSM click Manual ver. 1.01c CS, RST and AN). The board is designed to use aligned correctly, push the board all 3.3V and 5V I/O voltage levels. A LED diode the way into the socket. indicates the presence of power supply. 0 100000 026595
