Here is a DIY breakout board for the MMA7455L, an inexpensive three-axis accelerometer. It’s got all the decoupling capacitors and pull-up resistors specified by the accelerometer datasheet.There’s also an interfacing tutorial for the Arduino.
We like this chip because it’s cheap, but the LGA package is difficult to solder. If you’re not up for soldering the tiny chip, check out our assembled MMA7455L breakout board. Get the MMA7455L breakout board for $15 at Seeed Studio.
