The KXCJ9 is a high-performance, ultra-low-power, tri-axis accelerometer designed for mobile applications. It offers our best power performance along with an embedded wake-up feature, Fast-mode I²C and up to 14-bit resolution. The KXCJ9 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 KXCJ9 sensor offers improved shock, reflow, and temperature performance, and the ASIC has internal voltage regulators that allow operation from 1.8 V to 3.6 V within the specified product performance. Pin compatible with KXTI9 and KXTF9.

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.
