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 Gyro click 2 3 4. Essential features 1. Introduction Gyro Click with its L3GD20 IC is capable of providing the measured angular rate to the external world through a digital 2 interface (I C, SPI). The L3GD20 has a full scale of 250/ 500 / 2000 dps and is capable of measuring rates with a user- Turn the board upside down so that Turn the board upward again. Make sure selectable bandwidth. All these features bottom side is facing you upwards. Place to align the headers so that they are make this board ideal for gaming and virtual shorter parts of the header pins in both perpendicular to the board, then solder the reality input devices, motion control, GPS soldering pad locations. pins carefully. navigation systems and more. Gyro Click is an accessory board in mikroBUS form factor. Its a compact 3. Plugging the board in and easy solution for adding gyroscope click to your design. It features L3GD20 three- Once you have soldered the headers your axis digital gyroscope module. Gyro Click board is ready to be placed into desired BOARD communicates with the target board mikroBUS socket. Make sure to align the www.mikroe.com microcontroller via mikroBUS SPI (MOSI, cut in the lower-right part of the board 2 MISO, SCK, CS), I C (SDA, SCL), INT and RST with the markings on the silkscreen at the Gyro click Manual lines. The board is designed to use 3.3V mikroBUS socket. If all of the pins are ver. 1.01 power supply only. LED diode (GREEN) aligned correctly, push the board all indicates the presence of power supply. the way into the socket. 0 100000 0231986. SMD Jumpers 5. Gyro Click Board Schematic The Gyro Click board communicates with the main board microcontroller 2 via I C or SPI interface depending on the position of the J1, J2 and J3 SMD jumpers. These 2 jumpers are soldered in I C interface position by default. There is an option to select the alternate address with jumper J4 in the case 2 of I C interface (default position is logic 1).
