I would like to know the best way to wire a switch to turn off a LiPo-powered M0. I can place a switch between USB+ and the LiPo+, but the battery won't charge under USB unless the switch is on. I would like to charge while the switch is in the OFF position so the M0 won't keep drawing current. For example, I use the EN pin on the Adafruit Feather to accomplish this.
