Skywire Click Board™

Product Code: MIKROE-2405

The Skywire™ Click Board™ is an adapter, which hosts NimbeLink/Skywire™ cellular modems (using stacking headers) to MikroElektronika development boards. 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 Board™ are not included in this offer. ADDITIONAL MIKROBUS™ SOCKET The Skywire™ Click Board™ 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. SPECIFICATIONS Type Adapter Applications Developemnt of 2G, 3G or LTE applications by using Skywire cellular modems On-board modules MCP1826 LDO regulator Key Features Additional socket for mini sized click board™, MCP1826 LDO regulator, 3.3V or 5V power supply Interface GPIO,UART Compatibility mikroBUS Click board size L (57.15 x 25.4 mm) Input Voltage 3.3V or 5V PINOUT DIAGRAM This table shows how the pinout on Skywire click corresponds to the pinout on the mikroBUS™ socket (the latter shown in the two middle columns).
