CP2102 USB to TTL UART Serial Convertor Module

Description

This is the CP2102 USB 2.0 to TTL UART serial converter module. This is a great little tool for embedded systems that require a serial connection to a computer. The board can simply attach to a USB bus and will appear as a standard COM port.

Features :

1. Brand new and high quality
2. Included USB transceiver, without external circuit device
3. Includes a clock circuit and power-on reset circuit
4. With 3.3V and 5V dual power output
5. With three LEDs: power indicator, data reception indicator, the data transmission indicator, working status
6. Meet the USB2.0 specification requirements
7. SUSPEND pin supports USB suspend state
8. With self-recovery fuse. In the event of the accidental short circuit, it can effectively protect your computer USB port and Downloader
9. Asynchronous serial data bus compatible with all handshake and modulation controller interface signals
10. The supported data format is 8 data bits, 1 stop bit and parity bits
11. Connotation 512 byte receive buffer and 512 bytes transmit buffer
12. Supports hardware handshaking or X-ON/X-OFF

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
