UART is the two-wire serial link (TX and RX) most boards use to take new code and print messages, and this board turns it into a COM port on your computer.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eIt uses the \u003cstrong\u003eCP2102N\u003c\/strong\u003e from Silicon Labs and a \u003cstrong\u003eUSB-C\u003c\/strong\u003e connector. The 6-pin FTDI header has the pin order most USB serial adapters use, so it plugs straight into boards such as the Arduino Pro Mini. The DTR pin resets that kind of board for you before each upload.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eA slide switch sets the VCC pin to \u003cstrong\u003e5 V or 3.3 V\u003c\/strong\u003e, so the adapter can also power the board you are programming. The TX and RX lines stay at \u003cstrong\u003e3.3 V logic\u003c\/strong\u003e in both positions.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eTwo more headers give you every other line on the chip: RTS, CTS, DSR, DCD and RI, four GPIO pins, the suspend outputs and the 5 V and 3.3 V rails. TX, RX and power LEDs show what the board is doing.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eNote:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe UART pins use 3.3 V logic.
