The KXTF9 is a very popular high-performance, low-power, tri-axis digital I²C accelerometer with integrated orientation, Directional tap/double-tap, activity monitoring and motion-detection algorithms. The KXTF9 offers user-selectable ranges of ±2g, ±4g or ±8g as well as 8-bit and 12-bit resolution. The KXTF9 is delivered in a 3 x 3 x 0.9 mm, 10-pin, LGA package with an operating temperature range of -40°C to +85°C. The KXTF9 operates from a 1.8 V to 3.6 V DC supply (factory-programmable).

Not Recommended for New Designs.

IoT Evaluation and Development Kit Cart Kionix's IoT evaluation kit utilizes hardware platform based on Nordic Semiconductor's Bluetooth LE SoC. The compact (27/32mm x 4.2mm), highly integrated modular sensor system integrates Kionix's accelerometer (KX122-1037), combo accel-mag (KMX62-1031), and combo accel-gyro (KXG07) sensors along with ROHM's barometric pressure sensor (BM1383AGLV). Additional sensors can be evaluated using the add-on board that can fit inside the kit. This enables measurement of 3D acceleration, 3D magnetism, 3D rotation, air pressure, and temperature, making it ideal for training, prototyping, and initial set development of IoT and wearable applications.
