Frequently Asked Questions (FAQ)

  • Q: Where can I download the CP2102 driver?

    A: 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. more

  • Q: Where can I find information about the CP2102 USB to UART bridge controller?

    A: Note: The CP2102 is not recommended for new designs. For newer designs, the CP2102N devices offer compatible footprints and are recommended for use instead of the CP2102. The CP2102 USB to UART Bridge provides a complete plug and play interface solution that includes royalty-free drivers. This USB 2.0 compliant device includes 0 digital I/O pins and is availble in a 5x5 mm QFN28 package. more

  • Q: How do I connect a CP2102 bridge with ESP8266?

    A: This instructable will cover the basic steps that you need to follow to get started with the ESP8266 ESP-12. A lot of this content is already out there, but I had a hard time getting everything in place, and the different tutorials can cause a great deal of confusion, which is why I have tried to make the simplest setup possible. more

  • Q: How do I connect a CP2102 with the Arduino Pro Mini board?

    A: When I ordered a bunch of Arduino Pro Mini clones I didn't notice that these don't come with an integrated USB-to-Serial adapter (in fact I needed Arduino Nano - well, I was relative new into this). So to get a change to use them I've also ordered a CP2102 board that converts between USB and TTL. Since it took a while for me to figure out how to use that I will document it here. more

  • Q: Where can I find a PCB board for the CP2102 USB to TTL bridge?

    A: CP2102 chip from SiLabs is a single chip USB to UART bridge IC. It requires minimal external components. CP2102 can be used to migrate legacy serial port based devices to USB. Hobbyists can use it as a powerful tool to make all kinds of PC interfaced projects. This module help all those who are comfortable with RS232/Serial Communication protocol, to build USB devices very easily. more

  • Q: How do I get started with the CP2102 module?

    A: The CP2102 Breakout Board is a great tool for embedded systems that require a serial connection to a computer. The board attaches to the USB bus via a standard type B female connector, and appears as a standard COM port.This IC doesn’t require any external oscillator, has an on-board voltage regulator, and uses 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. more
