CP2102 USB to UART Bridge Driver


The CP2102 USB to UART is a plug and play compliant and are also USB 2.0 compliant. You can also see other drivers for the UART such as the FT232r USB UART driver as well as the FT232R USB UART which you will also find on this website. The hardware ID for the CP2102 USB to UART Bridge. The hardware ID “USB\VID_10C4&PID_EA601” uniquely identifies the CP2102 USB to UART Bridge device in the Windows operating system.

This article covers the CP2101, CP2102, CP2103, CP2104, CP2105 and CP2108 USB to UART bridge devices. This will show you how to obtain the port number of a specific CP210X device be this the CP2102 or any other devices in this range of bridges. Note that the vendor ID (VID), product ID (PID) and serial number determine the port number of the device.

CP2102 USB to UART Bridge DriverThe CP2102/9 USB-to-UART Bridge Controller allows you to update RS232 designs to USB using minimum  components and PCB space. The CP2102/9 also includes a USB 2.0 full-speed function controller as well as a USB transceiver, oscillator, the EEPROM or in some cases the EPROM, as well as an asynchronous serial data bus (UART) with full modem control signals. See also the CP2102 driver and Installing the CP2102 Driver as well. Download the CP2102 driver Windows 10 below.

With the on-chip programmable ROM you can also customise the USB Vendor ID, Product ID as well as the Product Description String, Power Descriptor, Device Release Number, as well as the Device Serial Number. This can be changed and programmed via the USB connection from your computer. This is the easiest way to setup and test the CP2102 USB to UART Bridge device. See the cp2102 driver listed below.

Difference between CP2102 and CH9102F

The CP2102 and CH9102F are like those translator gadgets that turn USB language into UART language, but they’ve got some differences:

  1. USB Stuff: The CP2102 uses a CP2102 USB to UART bridge, while the CH9102F uses a CH340G chip. The CH340G is kind of like that friend who sometimes messes up; it’s not as stable and might give you more trouble. On the other hand, the CP2102 is like the reliable friend who doesn’t cause many problems.
  2. Pin Party: The CH9102F has 6 GPIO pins (like special communication lines), while the CP2102 has 4 GPIO pins. Having more pins on the CH9102F is like having more room for cool gadgets or tools if you’re into creating stuff.
  3. Money Matters: The CH9102F is a budget-friendly option compared to the CP2102. It’s like choosing the cheaper snack at the store that still tastes good.

Just remember, even though these gadgets do similar things, they’re not exactly the same. Always make sure the one you pick fits your needs and works with your setup.


Additional Hardware

Deciding between the CP2102 and the CH9102F really comes down to what your project needs. Here’s a breakdown in simpler terms:

  1. Reliability: If you want your project to run smoothly without hiccups, go for the CP2102. It’s like the trustworthy option that’s less likely to cause problems.
  2. Money Matters: If you’re on a tight budget, the CH9102F is the cheaper choice compared to the CP2102. It’s like picking the more affordable option that still gets the job done.
  3. Pin Power: If your project involves connecting more cool gadgets or tools, the CH9102F might be your go-to because it has 6 GPIO pins. It’s like having extra outlets for your electronic devices.

Just remember, make sure the one you pick matches what your project needs and works with your setup. See the cp2102 driver download below. This is the latest cp2102 usb to uart bridge controller driver Windows 10 64-bit driver.
