This triple-axis accelerometer is a carrier board for the Freescale MMA7341LC XYZ-axis accelerometer, a great low-g sensor with analog voltage outputs and adjustable sensitivity (±3 g or ±9 g), and a 0g-detect digital output that signals when the board is in free-fall (±3 g sensitivity setting only). The board has a 3.3V linear regulator that enables an input voltage range of 2.2-16 V. The breakout board has a 0.1″ pin spacing making it easy to use with standard solderless breadboards and 0.1″ perfboards.

This three-axis accelerometer is a breakout board for Freescale’s MMA7361LC and MMA7341LC MEMS (micro-electro-mechanical systems) low-g accelerometers. 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 includes a 3.3V 50mA ultra-low-dropout linear voltage regulator, which allows the accelerometer breakout board to accept a wide range of input voltages (2.2-16 V) with power to spare for additional 3.3V components. The accelerometer’s pins are 0.1″ spaced to work well with standard solderless breadboards and 0.1″ perfboards.

The two versions of this board provide different sensitivity options. Boards marked with a black X, the MMA7361LC 3-axis accelerometer carrier, offers selectable ±1.5g or ±6g sensitivities, and boards marked with a red X, the MMA7341LC 3-axis accelerometer carrier, offers selectable ±3g or ±9g sensitivities. We also sell two smaller versions of this carrier board without the voltage regulator: the MMA7361LC 3-axis accelerometer carrier, and the MMA7341LC 3-axis accelerometer carrier.
