3.20. Camera Interfaces
Based on standard MIPI_CSI video input interface, SC20 series supports two cameras (2-lane + 1-lane),
and the maximum pixel of the rear camera can be up to 8 MP. The video and photo quality are
determined by various factors such as the camera sensor, camera lens quality, etc. It is recommended to
select a proper camera model, according to the specification of cameras verified and recommended by
Quectel.
The following models of camera sensors have been verified by Quectel:
For rear camera: Hi843 of SK Hynix, T4KA3 of TOSHIBA
For front camera: Hi259 of SK Hynix, SP2508 of SuperPix
3.20.1. Rear Camera Interface
The rear camera realizes transmission and control via its FPC and a connector which is connected to the
module. The rear camera interface integrates a two-lane MIPI_CSI for differential data transmission, and
it supports up to 8 MP camera.
The pin definition of rear camera interface is shown below.
