MMA7455L is an inexpensive 3-axis accelerometer with adjustable measurement range of 2/4/8g. It can communicate with microcontrollers through an SPI or I2C interface.
This chip is only a few dollars in onesies, but it comes in a leadless LGA-14 package. It’s a challenging chip to solder, so we though a inexpensive breakout board might be useful.
- 2/4/8g selectable
- 10bit or 8bit output
- force and pulse detection with interrupt
- I2C and SPI interface
What can you do with it? We’re using it to track hand motion with the USB POV Toy.

Get the MMA7455L breakout board for $15 at Seeed Studio. That’s about $5 cheaper than other accelerometer breakouts we’ve seen recently.
