NOTE
LDO4_2V8 (keeps ON @ idle state) is used for power supply for TP VDD by default and it can provide
200 mA current.
3.18. Camera Interfaces
Based on MIPI CSI standard, the module supports 2 cameras (2-lane + 1-lane): 1-lane MIPI for front
camera which supports up to 2 MP and 2-lane MIPI for rear camera which supports up to 8 MP. The video
and photo quality is determined by various factors such as the camera sensor, camera lens quality, etc.
