SKU: IFT00016-2 Category:


This is next generation CP2102 USB/TTL Breakout Board with Additional Signals which are not present in other similar Converters. 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 via a standard type B female connector 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 re-programmable 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.

Supported OS

  • Windows XP/Server 2003/Vista/7/8/8.1,
  • Windows 2K,
  • WinCE 6.0 (2.1), WinCE 5.0 (2.1)
  • Macintosh OSX (v3.1)
  • Linux 3.x.x, Linux 2.6.x
  • Android 4.2


  • Implements full v2.0 USB protocol
  • On board status indicator lights for RX and TX
  • Internal 1024 Bytes EEPROM for device ID and Product Description strings
  • Internal 640 Byte TX buffer
  • Internal 576 Byte RX buffer
  • Absolute Maximum Ratings table in datasheet suggests that Voltage on any I/O Pin or RST with respect to GND can be upto 5.8V. Which indirectly implies that the Input pins are 5.0V tolerant and can be connected with microcontroller or embedded boards running at 5.0V without requiring voltage level translation.
