The CrazyF411 ELRS flight controller comes with an integrated UART 2.4GHz ExpressLRS receiver and 20A Blheli_s ESC (Bluejay firmware pre-installed) which supports 2-4s. Bigger Mosfet supports up to 20A currents for 2-4S toothpick or long-range FPV drones.  The 2.4GHz ExpressLRS receiver is equipped with the SX1280 radio frequency chip with high sensitivity, high packet rate, and low latency, this flight controller is the one that all Race/Freestyle pilots have been waiting for.

Unlike most AIO boards, the built-in ELRS receiver uses UART communication with MCU, it’s like a separate ELRS receiver, which can be updated by Betaflight pass-through or WIFI, very simple.  Most built-in ELRS receivers on AIO boards use SPI, which cannot be updated separately through ELRS software.

Binding Procedure:

  • Supply power to the flight controller by plug USB, wait until the green LED on the FC is off, immediately turn off the power, and then repeat again the above steps. When the FC is powered on for the third time, the green LED light will start to double-flash, which means that the RX enters the binding mode
  • Please make sure your ExpressLRS tx module firmware is v3.x.x. And go to ExpressLRS.lua from “TOOLS” menu of your radio transmitter. Then hit [Bind] to binding with the onboard ExpressLRS receiver. The green LED should blinking slowly first then turn to solid, that means binding was successfully. If the green led still keep double flash after binding ,please change Model Match tab value from “off” to “on” or from “on” to “off”

Receiver LED Status:

Green LED solid means bind successful or RC link established; Green LED double-flash means get into bind mode; Green LED flash slowly means no RC signal input from TX module; Green LED continuous flash fast means ExpressLRS wifi enabled.
