The STMicroelectronics VD56G3 is a 1.5 M pixel global shutter image sensor
|
|
with an active array size of 1124 x 1364 (portrait orientation). It is
|
|
programmable through I2C, the address is fixed to 0x10. The sensor output is
|
|
available via CSI-2, which is configured as either 1 or 2 data lanes. The
|
|
sensor provides 8 GPIOS that can be used for external LED signal
|
|
(synchronized with sensor integration periods)
