Datasheet

Add the breakout board:
Place the breakout board over the pins.
(You can prop up the free edge of the board with some
extra pins to better align it for soldering.)
And Solder!
Be sure to solder all pins for reliable electrical contact.
(For tips on soldering, be sure to check out our Guide to
Excellent Soldering
(https://adafru.it/aTk)
).
Wiring:
You'll need to power the breakout, you can power it from 3V-5VDC, connect ground to GND and VCC to our power
supply (3-5V)
The L3GD20 breakout board supports both I2C and SPI communication. I2C requires the fewest connections, so we
will start with that:
Wiring for I2C:
I2C requires only 2 pins (in addition to VCC and ground).
