MMA7341L 3-Axis Accelerometer ±3/11g

SKU : MMA7341L

This tiny triple-axis accelerometer is a basic carrier board for the Freescale MMA7341L XYZ-axis accelerometer, a great low-g sensor with analog voltage outputs and adjustable sensitivity (±3 g or ±11 g). Our breakout board has the form factor of a 10-pin DIP package, which makes it easy to use with standard solderless breadboards and 0.1" perfboards, and the unit is smaller than competing products, all at a lower price. The board operates from 2.2 to 3.6 V.

Overview

This tiny three-axis accelerometer is a breakout board for Freescale’s MMA7361L (175k pdf) and MMA7341L (175k pdf) MEMS (micro-electro-mechanical systems) low-g accelerometers; we therefore recommend careful reading the appropriate datasheet for your particular board before using this product. The MMA7361 and MMA7341 are great ICs, but their small, leadless packages makes them difficult for the typical student or hobbyist to use. This carrier board includes all of the components in the part’s recommended connection diagram and breaks the pins out to a 0.5"×0.4" (12.7×10.2 mm) 10-pin DIP form factor that is easy to use with standard solderless breadboards and 0.1" perfboards.

The two versions of this board provide different sensitivity options: the MMA7361L carrier offers selectable ±1.5g or ±6g sensitivities along with a 0g-detect output that goes high when the board is in free fall; the MMA7341L carrier offers selectable ±3g or ±11g sensitivities (but has no 0g-detect output).
