3.19. Camera Interfaces

Based on standard MIPI CSI video input interface, SC20-WL module supports two cameras, and the
maximum pixel of the rear camera can be up to 8MP. The video and photo quality is 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

3.19.1. Rear Camera Interface

The rear camera realizes transmission and control via its FPC and a connector which is connected to the
module. SC20-WL rear camera interface integrates a two-lane MIPI CSI for differential data transmission,
and it maximally supports 8MP cameras.
The pin definition of rear camera interface is shown below.
