	Taking the "Woodpecker" USB UART adapter as an example, its pins should be connected to the pins of the "EXP" header as described in the table below, with the "5V" and "3V3" pins of the "Woodpecker" left unconnected. The voltage selection jumper found on the "Woodpecker" must be placed in the "3V3" position, as silkscreened on the top side of the "Woodpecker" PCB.
