CP2102 USB to TTL Converter
CP2102 USB to TTL UART Converter
The CP2102 USB to UART/TTL Converter Module provides a serial port for your computer, i.e. a virtual COM port to connect to a serial device. The IC used CP2102 is stable and reliable. It supports baud rates from 300bps to 1.5Mbps and driver support for a wide range of Operating Systems. 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.
ThisCP2102 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.

1. What is the use of USB to TTL converter?
- The CP2102 USB to TTL Converter Module adds a serial port to your computer, allowing you to connect to a serial device via a virtual COM port. This module is used in development boards for debugging, as a microcontroller for PC communication, and programming.
2. Why do we need a USB to TTL converter?
- When using USB hubs, this allows for the simple configuration of a multi-serial system without the need for IRQ or DMA configuration. They have 600W protection between the USB port and TTL, which protects the PC from spikes or possible communication bus misconnections.
