MMA7455L accelerometer free PCB build

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 – we’ll send you a coupon code for the free PCB drawer. Get the MMA7455L breakout […]

DIY MMA7455L 3-axis accelerometer breakout

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 […]

MMA7455L accelerometer free PCB build

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 required tantalum caps so I didn’t order but it turns out I have a different […]

Week in (p)review: May 27, 2011

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 from Maker Faire Single-sided, through-hole USB IR Toy v2 Saleae Logic 16 update USB Infrared […]

Accelerometer controlled OLED 3D cube

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 available in the forum. Get the MMA7455L breakout board for $15 at Seeed Studio. Back […]

Free PCB Sunday: MMA7455L breakout board

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 PCBs are made through Seeed Studio’s Fusion board service. This week we’re giving away two […]

DEMO: MMA7455L 3-axis accelerometer

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 with interrupt I2C and SPI interface 3.3volts Get the MMA7455L breakout board for $15 at […]

NEW PRODUCT: MMA7455L 3-axis accelerometer breakout board

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 […]
