mikroElektronika Gyro click User manual

1. Introduction
Once you have soldered the headers your
board is ready to be placed into desired
mikroBUS™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at the
mikroBUS™ socket. If all of the pins are
aligned correctly, push the board all
the way into the socket.

4. Essential features
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
Turn the board upside down so that
bottom side is facing you upwards. Place
shorter parts of the header pins in both
soldering pad locations.
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.

Gyro click Manual
ver. 1.01
0 100000 023198
Gyro Click™is an accessory board in
mikroBUS™form factor. It’s a compact
and easy solution for adding gyroscope
to your design. It features L3GD20 three-
axis digital gyroscope module. Gyro Click™
communicates with the target board
microcontroller via mikroBUS™ SPI (MOSI,
MISO, SCK, CS), I2C (SDA, SCL), INT and RST
lines. The board is designed to use 3.3V
power supply only. LED diode (GREEN)
indicates the presence of power supply.
Gyro click
Gyro Click™ with it’s L3GD20 IC is capable
of providing the measured angular rate
to the external world through a digital
interface (I2C, SPI). The L3GD20 has a full
scale of ±250/ ±500 / ±2000 dps and is
capable of measuring rates with a user-
selectable bandwidth. All these features
make this board ideal for gaming and virtual
reality input devices, motion control, GPS
navigation systems and more.

Once you have done all the necessary
preparations, it’s time to get your click
board up and running. We have provided
the examples for mikroC, mikroBasic and
mikroPascal compilers on our Libstock
website. Just download them and you are
ready to start.

6. SMD Jumpers
The Gyro Click™ board
communicates with the
main board microcontroller
via I2C or SPI interface
depending on the position
of the J1, J2 and J3 SMD jumpers. These
jumpers are soldered in I2C interface position
by default. There is an option to select the
alternate address with jumper J4 in the case
of I2C interface (default position is logic 1).
