NOTE
TP is powered by LDO10_2P8 by default and LDO10_2P8 can output 150mA current. It is recommended
to use an external LDO power supply if dual-TP or other applications need to be supported.
3.21. Camera Interfaces
Based on standard MIPI CSI input interface, SC650T module supports 2 cameras (4-lane + 4-lane ), with
maximum pixels up to 24MP. The video and photo quality are determined by various factors such as
camera sensor, camera lens quality, etc.
