Assembly and Wiring

The board comes with all surface-mount components pre-soldered. The included header strip can be soldered on for convenient use on a breadboard or with 0.1" connectors. However, for applications subject to extreme accelerations, shock or vibration, locking connectors or direct soldering is advised.


Assembly:

Position the Header:

Cut the header to size if necessary. Then plug the header - long pins down - into a breadboard to stabilize it for soldering.

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
