The SHUTTLE BOARD BMA253 is an evaluation board with a built-in triaxial MEMS accelerometer for use in a wide range of applications. The board’s small size and low power consumption makes it ideal for applications where space is at a premium and prolonged battery life is necessary.

The BMA253 is commonly used in applications such as shock, vibration, tilt, and tilt-compensation measurements, gaming, and for device orientation sensing. When used in these types of applications, the BMA253’s built-in dynamic range of up to ±20 g enables reliable measurement of dynamic acceleration, resulting in more accurate measurement results.The BMA253 utilizes MEMS-based, high-performance seismic sensing technology, which leverages small capacitive accelerometers to detect physical accelerations. It incorporates two capacitive MEMS structures and an IC for signal conditioning. The top structural element frames the substrate, forming a set of air chambers that eliminate any external motion influences, and reducing overall package size. The elements interconnected by the substrate form a bridge-like structure, with a single quadrant capacitor on each arm of the bridge. This multi-element structure is sensitive to acceleration and provides robustness against an external stressor, thereby improving performance and accuracy.

The BMA253\'s signal conditioning IC contains control logic and timing, amplifiers and filters, and an analog-to-digital converter. The analog signal from the MEMS is amplified and conditioned by the signal conditioning logic, and filtered before it is output in a digital format. The digital signal can then be read out via SPI or I2C, allowing the accelerometer values to be stored, retrieved, and processed.

The BMA253 evaluation board offers an easy way to quickly test and evaluate the various features and performance of the accelerometer, making it ideal for customers that want to develop their own motion sensing applications. The board includes an on-board thermal sensor, allowing customers to accurately measure the temperature range of their application. Additionally, the board also contains several digital isolators for further protection against external interference.

In conclusion, the SHUTTLE BOARD BMA253 is an excellent choice for a variety of MEMS accelerometer applications and offers great performance and accuracy. With its small size and low power consumption, it is ideal for applications where space and battery life are both at a premium.
