1.Why are there two pins per I / O?
2.Which I / O can be used as a UART serial connection?
3.Which I / O can be used as 3.3V power supply?

- I'm not sure what you mean.
- Any IO_* pin can be used for any FPIOA function.
- Every power group can use 3.3V. Each pin in the FPIOA can sink a max of 50 mA.
