There are a few errors that you may want to correct.
- The first image is “The Naze 32 Revision 6 pinout”. On right hand side UART 2 RX should be UART1 RX. Both of those pins are on the same UART.
- The second picture is a zoom in on the first. The indicated 5V and Gnd are really Buzzer and Voltage Monitor. The are correct in the first image.
- The third picture “Typical Naze32 Connection diagram” has no 5V power. The Battery Voltage Moniter does not power the board.
