BETAFPV ExpressLRS Recovery Dongle CP2102 USB Type-C to TTL Adapter for ELRS Firmware Recovery

Description

Overview

The BetaFPV ExpressLRS Recovery Dongle is an FTDI USB to TTL module based on the CP2102 bridge controller for firmware upgrade and recovery of ESP32 & ESP8XX-based ELRS receivers and FPV goggles backpack. It is designed to help recover (unbrick) an ELRS receiver after a failed update (for example, missing bootloader) and also supports flashing via UART.

Key Features

• Firmware recovery for ELRS devices after failed WiFi upgrade or passthrough.
• Solder-free operation with spring probe pins for direct connection.
• CP2102 USB-to-serial chipset.
• Type-C USB connection to computer.
• Enclosed case for improved durability and portability.
• Computer OS support: XP, Windows 7/8 (32-bit, 64-bit), Windows 10/11 (32-bit, 64-bit), Linux, Mac.

Details

A compact CP2102 USBC to TTL tool for recovering (unbricking) ExpressLRS receivers after a failed firmware update.

Clear protective enclosure with clearly labeled TX/RX/5V/GND pins for quick, mistake-free wiring.

Solder-free spring probe connection helps access ELRS pads for recovery and UART flashing without permanent mods.

Straightforward pin mapping keeps TX/RX and power connections consistent between the dongle and the probe board.

Pinout labels make it easy to access BOOT/EN and 3.3V where supported for ESP-based ELRS recovery.

Built for working with ESP32/ESP8XX-based ELRS receivers and compatible FPV goggles backpacks during firmware recovery.
