Flashlight Interfaces; Sensor Interfaces - Quectel SG865W Series Hardware Design

4.14.2. Flashlight Interfaces

The module supports 3 flash LED drivers, FLASH_LED1 and FLASH_LED2 are both with maximal output
current up to 1.5 A per channel in flash mode and 300 mA in torch mode. FLASH_LED3 with maximal
output current up to 0.75 A in flash mode and 300 mA in torch mode.
