+description: |-
+ The STMicroelectronics VD55G1 is a global shutter image sensor with an active
+ array size of 804H x 704V. It is programmable through I2C interface. The I2C
+ address is fixed to 0x10.
+ Image data is sent through MIPI CSI-2, which is configured as only 1 data
+ lane. The sensor provides 4 GPIOS that can be used for external LED signal
+ (synchronized with sensor integration periods).
