https://devzone.nordicsemi.com/f/nordic-q-a/6330/powering-nrf51-dongle-from-a-batteryI want to power the dongle from a 5V battery but don&#39;t want to solder directly to USB pads at the risk of ruining them. Can I put the 5V from the battery at the Vin point? Normally the board is supplied power at Vbus point.
