Fcobcn 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 – … Read more
In our previous Workshop Video we mentioned we asked Pietja to solder up those pesky MMA7455L accelerometers. Here is how he got around to doing it. Check out the pics and his instructions below. Ian asked me to solder some … Read more
Gary built two free MMA7455L accelerometer breakout boards. The MMA7455L is a 3-axis accelerometer with I2C and SPI interfaces. I’ve just received and put together the PCBs I got (they even worked). Thanks Ian for the free PCB!! If you … Read more
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 … Read more
Tayken built a free MMA7455L accelerometer breakout board. The MMA7455L is a 3-axis accelerometer with I2C and SPI interfaces. As I finally had my accelerometer, I’ve decided to solder it up using electric skillet method. I thought I had the … Read more

SineWave built a free MMA7455L accelerometer breakout board. We’re always surprised how popular these PCBs are. Nice use of solder paste and stenciling. Turned out pretty awesome and they work great. Used an overhead transparency as a stencil. If you … Read more
Eric Pan (Seeed Studio) and Ian (me). Facebook free PCB Friday is on the way. Don’t forget to share your current project in the comments or the forum. Here’s a summary of major developments over the last week: We’re back … Read more
tagno25 built a free MMA7455L breakout board. Nice work soldering that beast of a 14-LGA chip. 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 … Read more
Markus used an MMA7455L 3-axis accelerometer to detect the direction of the gravity in this cool demo: I am using the MMA7455L breakout board to control a 3D cube displayed on a (SPI-modified Seeedstudio) OLED display. My MMA7455L library is … Read more
Our cheap 3-axis accelerometer MMA7455L breakout board is back in stock at Seeed Studio. This version has an X/Y/Z axis indicator on the silkscreen. Get one for $15.
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our … Read more
Here’s a demo of the MMA7455L 3-axis accelerometer in SPI mode using the Bus Pirate. We’ve got this sensor on a breakout board for $15. The MMA7455L has: 2/4/8g selectable measurement range 10bit or 8bit output force and pulse detection … Read more
