title: ROHM/Kionix KX022A, KX132/134-1211 and KX132/134ACR-LBZ Accelerometers

maintainers:

description: |
  KX022A, KX132ACR-LBZ and KX132-1211 are 3-axis accelerometers supporting
  +/- 2G, 4G, 8G and 16G ranges. The KX134ACR-LBZ and KX134-1211 support
  +/- 8G, 16G, 32G and 64G. All the sensors also have variable output
  data-rates and a hardware-fifo buffering. These accelerometers can be
  accessed either via I2C or SPI.
