Teensi 4.1 External Power OR USB


New member
Hey hi hello - I'm looking to drop a 4.1 into a larger project and would like the ability to switch between either battery power or USB. Presumably leaving the pad between VUSB and VIN uncut would lead to potential backcurrent issues, yes? Would it be suitable to cut the pad and then run the VUSB pin to VIN through a diode, and run my source through a diode to VIN?
