The module itself are pretty reference in design similar to this:
Module load are COB LED +12V light. +Vbat are Li-Ion power which also powers the MCU through 3.3V LDO and I want to enable/disable module & LED from MCU.
PS: I know the DC-DC IC has the ENABLE pin, but it's hard wired to the Vin+ on board and I don't want to deal with cutting traces.
I'm also aware it's possible to control LED by adding MOSFET to the LED GND line but this way the module will be always powered up and I want to save battery power by turning it off completely when not used.
