This is the CP2102 6-pin 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.

 

This CP2102 doesn’t require any external oscillator, it onboard-board voltage regulator, and it even uses a reprogrammable internal EEPROM for the device description. The full hardware UART has flow control for baud rates from 300bps to 921600bps.

 

This breakout also allows you to connect the TX/RX pins of your favorite microcontroller or serial application to the RX/TX pins of the breakout, creating a simple serial cable replacement.

Features:

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

 

Package Includes:

• 1 x CP2102 6-pin USB 2.0 to TTL UART Serial Converter Module
