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 Thunder click 2 3 4. Essential features 1. Introduction Thunder click with its AS3935 IC and MA5532 coil antenna detects the presence and proximity of potentially hazardous lightning activity in the vicinity and provides estimated distance to the center of the storm. It can also provide information on Turn the board upside down so that Turn the board upward again. Make sure the noise level. All these features make bottom side is facing you upwards. to align the headers so that they are this board ideal for weather stations, sports Place shorter pins of the header into the perpendicular to the board, then solder the equipment, pool safety, UPSs, GPSs, watches, appropriate soldering pads. pins carefully. cellular phones and many more. Thunder click is an accessory board in mikroBUS form factor. Its a compact and 3. Plugging the board in easy solution for adding lightning sensor to click your design. It features AS3935 lightning Once you have soldered the headers your sensor as well as MA5532 coil antenna. board is ready to be placed into desired BOARD Thunder click communicates with the mikroBUS socket. Make sure to align the www.mikroe.com target board microcontroller via mikroBUS cut in the lower-right part of the board SPI (MOSI, MISO, SCK, CS) and INT lines. The with the markings on the silkscreen at Thunder click Manual board is designed to use 3.3V or 5V power the mikroBUS socket. If all of the pins are ver. 1.01 supply. LED diode (GREEN) indicates the aligned correctly, push the board all presence of power supply. the way into the socket. 0 100000 024317 6. SMD Jumpers 5. Thunder click Board Schematic VCC VCC VCC VCC There is one zero-ohm SMD jumper J1 used to select whether 3.3V or 5V power supply is R1 C4 C5 used.
