Dmmedia built a free MMA7455L accelerometer breakout board. The MMA7455L is a 3-axis accelerometer with I2C and SPI interfaces.
If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send you a coupon code for the free PCB drawer.
Get the MMA7455L breakout board for $15 at Seeed Studio.
