Add the Breakout:
Align the breakout board and place it over the header
pins on the breadboard.
And Solder!
Be sure to solder all pins to assure good electrical
contact.
I2C Wiring:
The ADXL345 Breakout has an I2C address of 0x53. It can share the I2C bus with other I2C devices as long as each
device has a unique address. Only 4 connections are required for I2C communication:
GND->GND
VIN->+5v
SDA->SDA (Analog 4 on "Classic Arduinos")
SCL->SCL (Analog 5 on "Classic Arduinos")
The Adafruit breakout has level shifting and regulation circuitry so you can power it from 3-5V and use 3V or 5V logic
levels for i2c
