It carries the MCP1826 low dropout regulator from Microchip. Skywire™ click is designed to run either on 3.3V or 5V power supply. The click communicates with the target MCU over UART interface, and the following mikroBUS™ pins: PWM, AN, INT, RST, CS. NOTE: the Skywire™ modem and the Thermo 3 click are not included in this offer. Additional mikroBUS™ socket Skywire™ click has the capability to host an additional mini sized click board™. It also has its own power supply to make the needed voltage for the modules. Skywire cellular modems Skywire™ cellular modems are the smallest on the market today. This product family from NimbeLink covers everything from 2G and 3G to LTE. They all share the same footprint and pinout, and are flexible for implementation.

This is a simple main function, which excepts a call and replies with an SMS to caller. The content of the SMS is the current temperature measurement in degrees Celsius. 01: void main() 02: { 03: measure_f = false; 04: system_init(); 05: skywire_power_on(); 06: at_init( rsp_handler, UART3_Write, buffer, sizeof( buffer ) ); 07: at_cmd_save( "+CLCC", 1000, NULL, NULL, NULL, callerid_handler ); // Assigning caller ID handler 08: at_cmd_single( "AT" ); 09: at_cmd_single( "AT+CSCS="GSM"" ); 10: at_cmd_single( "AT+CMGF=1" ); 11: while( 1 ) 12: { 13: at_process(); 14: 15: if( measure_f ) 16: { 17: measure_temp(); 18: at_cmd_single( "AT+CLCC" ); 19: at_cmd_single( "ATH" ); 20: Delay_ms( 2000 ); // Delay needed after ATH 21: reply_to_caller(); 22: measure_f = false; 23: } 24: } 25: } Jumpers and settings The following table describes the functions of the onboard jumpers.
