Tri-Axis, 1.5g - 6g, Ultra Low Noise Digital (SPI) and Multiplexed Analog, 3x5x0.9mm LGA - KXRB5-2042

The KXRB5 is a high-performance, low-power tri-axis accelerometer offering multiplexed analog or SPI digital communications, an integrated 4-channel multiplexer and embedded freefall and high-g drop detection algorithms. The KXRB5 offers a factory-programmable g-range of ±1.5g to ±6g and is delivered in a 3 x 5 x 0.9 mm, 14-pin, LGA package with an operating temperature range of -40°C to +85°C. The KXRB5 operates from a 2.5 V to 5.25 V DC supply (factory-programmable).



  • Ultra low noise; well suited for precise tilt applications
  • Analog or Digital
  • Excellent performance over temperature

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.
