  31 +description: |-
  32 +  The Arducam 1/1.7-Inch 64Mpixel CMOS active pixel digital image sensor
  33 +  with an active array size of 9248 x 6944. It is programmable through
  34 +  I2C interface. The I2C address is fixed to 0x1A as per sensor data sheet.
  35 +  Image data is sent through MIPI CSI-2, which can be configured for operation
  36 +  with either 2 or 4 data lanes.
