CP2102 USB TTL Programmer

This is the USB to Serial CP2102 Breakout Board. 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.

Thes CP2102 doesn’t require any external oscillator, it has an on-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

• Built-in USB to TTL Transfer chip CP2102 Replace FT232
• Designed to be used for USB to TTL Electronic Projects.
• TTL interface output, easy to connect to your MCU.
• Dual 3.3V and 5V Power Output, Work with 3.3v and 5v Target Device
• DTR pin used to programmatically reset target microcontroller

Driver
The CP210x USB to UART Bridge Virtual COM Port (VCP) drivers are required for device operation as a Virtual COM Port to facilitate host communication with CP210x products. These devices can also interface to a host using the direct access driver. These drivers are static examples detailed in application note 197: The Serial Communications Guide for the CP210x, download an example below.
