Kit Overview

The Freescale's TWRPI-MMA6900TWRPI-MMA6900 is a Tower System plug-in board that contains the Xtrinsic MMA6900Q inertial sensor that can be used in automotive and industrial applications. The board is designed to interface to the Freescale Tower System, a modular development platform which aids in rapid prototyping and tool-reuse. An integrated Open-Source BDM, software tools, and examples provided with the development board make application development and debug quick and easy.

The MMA6900Q are dual axis, low g, xy sensors based on Freescale’s HARMEMS technology with an embedded DSP ASIC allowing for additional processing of digital or analog signals. The MMA6900Q has a ±3.5g full-scale range per axis. Xtrinsic MMA6900Q sensors are SafeAssure functional safety solutions.

Take your design to the next level with the Freescale Tower System. Freescale's modular development platform saves you months of development time now and in the future through rapid prototyping and tool re–use.

Interchangeable and reusable modules along with open source design files make it easy to customize your design and reduce low level design giving you more time to focus on differentiated solutions.
