I got given a Fio V3 but unfortunately the MicroUSB port is missing, not sure why. Is there any other way to program it? I'm thinking perhaps those 6 pins under the microcontroller?
Also can I still power the board? I notice it doesn't have a VCC or RAW pin like the Pro Micro version. I'm not to worried about using a battery, can I plug any matching voltage into the battery plug?
I tried looking through the schematics and tutorials on Sparkfun but don't really know what I'm looking at. Here are some relevant links anyhow:
