I want to connect my Teensy 3 to the serial port of a TP-Link MR-3020 router. This serial port gives me 3.3 V of power. Would that be enough for the teensy 3 if I do not need USB while the Teensy is connected to the router? Or should I try to tap 5V somewhere on the router (which is also possible, but mechaniclally more difficult.
TIA
