I'm using my old Serial Debug with stereo jack that I've prepare 2 year for the original Pinbook-A64 and it is working well on PBP.
It is using a cheap USB-TTL CH340 dongle purchased on eBay, they have a jumper to select either 3V3 or 5V.
I have about 15 of those dongles, since I leave them attached to almost all my ARM boards, "almost" because I will need to purchase maybe 5 more ... :-)
