Well, I was thinking that as I'd be selling these in a pack of 5 I might do an extra PCB with the relevant connector on it - I guess that could have a regulator (or just diodes), but to be honest I was thinking of skipping the power supply altogether and just having GND, RX and TX.
Obviously that extra PCB could have an FTDI chip on it too, but I think it's just all getting too complicated/expensive at that point.
The point of them would be to build them in to stuff, so you'd probably have a battery or power supply attached anyway. If you just wanted something to plug in and get going, you'd be better off with a Pico.
... but yes, the simple solution would be to make sure that you could stick an FTDI cable into a breadboard next to it.
