Pinouts:

• TX = Connect to Transmit Pin(TXD) of Micro controller. This pin is RX pin of CP2102 on board.
• RX = Connect to Receive Pin(RXD) of Micro controller. This pin is TX pin of CP2102 on board.
• RST = Normally Unconnected. Reset Pin for CP2102. Initiate a system reset by driving this pin low for atleast 15 µs.
• GND = Should be common to microcontroller ground.
• 3V3 = Optional output to power external circuit upto 50mA.
• 5V = Optional output to power external circuit upto 100mA
