Tri-Axis, User Selectable 2g, 4g, 6g, 8g, Ultra Low Power Digital, 3x3x0.9mm LGA - KXUD9-4100

The KXUD9 is a low-power, tri-axis accelerometer with either I²C or SPI communication protocols, a user-definable low-pass filter and embedded motion wake-up. The KXUD9 offers user-selectable g-ranges of ±2g, ±4g or ±8g and an auxiliary input for A/D conversion. It 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 KXUD9 operates from a 1.8 V to 3.6 V DC supply.

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.
