Universal CP2102 Driver Download For Windows 11 10 7 | Silicon Lab CP210x Driver

Many engineers, makers and hobbyists still use the devices with simpler older serial data protocols to communicate with the PC, but modern computers no longer support them in a simple way, making connection a challenge without the right adapter.

That’s where the USB to UART Bridge Controller comes in and which requires CP2102 driver download. This controller acts as a bridge between your USB port and serial protocol based devices which makes data transfer quick, stable, and hassle-free. Serial ports, it was once straightforward, but modern laptops no longer make it that easy.

Silicon Lab CP2102 is an all-in-one chip that includes a USB 2.0 controller, oscillator, transceiver, and memory, all packed neatly into a small 5×5 mm package. What makes it special is its ability to let your computer recognize a serial device as a standard COM port, which is promptly handled by Virtual COM Port (VCP) drivers.
