BetaFPV ExpressLRS Recovery Dongle – ELRS Receiver Recovery Device

The BetaFPV ExpressLRS Recovery Dongle is a compact USB-to-TTL module based on the CP2102 chip, designed for quick recovery or reflashing of ELRS receivers with ESP32 and ESP8XX microcontrollers. This device is useful when updates via Wi-Fi or standard passthrough/UART have failed, for example, due to a missing bootloader. The Recovery Dongle allows you to restore the functionality of ELRS Lite Receiver, ELRS Nano Receiver, ELRS Micro Receiver, and other compatible receivers without complex equipment.
