   * Default settings:  Power Voltage is set to 3.3V.  See the PIC. 1, from the right side, near the ‘3G SARA click’ PCB silk screen label. There is 0-Ohms Resistor, which can be reflowed to other position if it is a necessary 3G Modem to work on 5V Powered mikroBus^TM Systems.

   ** One connector for all boards:   The mikroBUS™ is specially developed By Mikroelektronika Pinout Standard.

PIC. 3  3G SARA Click: Pin-Description Diagram 

   When the Pin-1 is configured to provide the “Network status indication” its main function is to display – for example: on the LED indicator, the different modes by the different ways, as is following

   Network Status or STAT Pin-(1) represents the 3G network status – [H]:HIGH Level; [L]:LOW Level:

• No service (there is no network coverage or GSM Sim Card can’t be registered) – Constant Low State; 

• Registered home network is 2G – Cyclically Repeated: [H] – 100 ms, [L] – 2 s;

• Registered home network is 3G – Cyclically Repeated: [H] – 50 ms, [L] – 50 ms,  [H] – 50 ms, [L] – 2 s;

• Registered visitor has the roaming access to 2G network – Cyclically Repeated: [H] – 100 ms, [L] – 100 ms, [H] – 100 ms, [L] – 2 s; 

• Registered visitor has the roaming access to 3G network – Cyclically Repeated: [H] – 50 ms, [L] – 50 ms, [H] – 50 ms, [L] – 100 ms;

• If 2G or 3G network’s voice or data calls are enabled – Constant High State. 

   TxD & RxD – UART Data Transmit and Data Receive Pins.

   RTS & CTS – UART Request To Send  &  Clear To Send Hardware Handshake Supporting Pins.

   PWRKEY – Power ON and Power OFF  the 3G Modem.

   RI – Ring Indicator – for detecting the incoming call or Short Message Services (SMS) messages.

   +3v3 : Positive Battery or Power Source Terminal.

   GND : Negative Battery or Power Source terminal – GROUND.

mikroBUS™ Main Benefits:

• Ideal for Breadboards – ‘mechanical PCB’: mikroBUS™ standard pinouts is based on 0.1- inch (100 mils) pitch step between the pins and 0.9- inch distance between the two 8-pins rows,
• SPI – Serial Peripheral Interface,
• I²C – Inter-Integrated Circuit – SDA ( Serial Data ) and  SCL (Serial Clock) Pins,
• Analog inputs ,
• UART – Universal Asynchronous Receiver-Transmitter,
• Interrupt – Jump to Interrupt Subroutine Vector in the Program Memory,
• PWM – Pulse Width Modulation,
• RESET – Set the Program Counter to the First Program Memory Address / Code Segment Address – 0000h,
• Power supply pins – two separate power paths for 3.3V and 5V.
