* RX - The '''recieve''' line, aka the '''input'''.
{{warning|'''DO NOT CONNECT THE POWER PIN IF YOU DON'T KNOW YOUR DEVICE'S UART OUTPUT VOLTAGE!''' Most UART adapters will send 5v by default (although some give a or 3.3v option) by default and phones will usually use 1.8v (occasionally 3.3v). Plugging the power/VCC pin in when the voltages don't match on your adapter and device '''may kill it'''. See the "3.3v vs 1.8v" section at the bottom of this page.}}
To recieve logs, '''you will only need to connect the ground and RX wires'''. To send information through the serial console, you will also need to connect the VCC and TX wires.
