ExpressLRS Recovery Dongle (FTDI USB to TTL)


BetaFPV was among the first drone brands that joined the ExpressLRS team by adopting their high-performance Open Source Radio Control Link. The ELRS Recovery Dongle comes in help for those who brick their radio receiver when failed in updating or flash firmware by using the UART port instead of WIFI.
In a nutshell, the BetaFPV ExpressLRS Recovery Dongle is an FTDI USB to TTL adapter. Its ingenious design with spring probe pins allows a solder-free solution connection to unbrick your ELRS RX. It has a CP2102 chipset (USB to UART Bridge Virtual COM Port) and it is compatible with most ELRS receivers based on ESP32 and ESP8XX chips including BetaFPV ELRS Lite, Nano, and Micro receivers.
