CP2102 Driver Installation Guide (Windows)

The CP2102 is a USB-to-UART IC from Silicon Labs, used on several MicoAir telemetry products such as the LR900-F and LR24-F. The first time you connect a MicoAir radio to a Windows computer, you need to install the CP2102 driver.

Recommended: Silicon Labs official CP210x VCP Drivers — download the Windows package directly from the chip manufacturer.
