GSM Click is an add-on board in the mikroBUS form factor and is a perfect solution for adding a GSM/GPRS communication layer to your device. It features the Telit GL865-QUAD GSM/GPRS module which supports GSM/GPRS 850/900/1800/1900 MHz Quad-band frequency. The board contains a TXB0106 6-bit bidirectional voltage-level translator as well as a SIM card socket. GSM Click communicates with the target microcontroller via seven mikroBUS lines (RX, TX, INT, PWM, CS, RST and AN). The board uses a 3.3V power supply, but can communicate at either 3.3V or 5V voltage levels (selection by SMD jumper). An LED diode indicates the presence of power supply. |

GSM Booster is a pin-compatible replacement for the Telit GM862-QUAD module; retaining the same form factor as this popular, yet obsolete module. GSM Booster contains Telit's new GL865-QUAD GSM module, MMCX GSM antenna connector, SIM card holder and CSTP 50 pin vertical SMD molex connector (male) for further connection. It can be used on existing MikroElektronika development boards designed for the GM862. There are four zero-ohm SMD jumpers used to select whether Handsfree (HF) or Handset (MT) audio pins are used (soldered in the HF position by default). |
