Happymodel CrazyF411 ELRS AIO 4in1 Flight Controller Built-in UART 2.4G ELRS Receiver 20A ESC for Crux35 Toothpick FPV Racing Drone
Introduction:
The CrazyF411 ELRS flight controller comes with integrated UART 2.4GHz ExpressLRS receiver and 20 ABlheli_s ESC(Bluejay firmware pre-installed) which could support 2-4s. Bigger Mosfet could support high to 20 Acurrents would be better for 2-4S toothpick drone or long range FPV drone. And because 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 needed. The built-in ELRS receiver is UART communication with MCU, it??s the same like Happymodel EP1 which you can update firmware by betaflight pass-through or WIFI, very simple. The default firmware is ELRS V3.0.1. This flight controller would be used for Crux35 to instead ELRS X1 flight controller.

Binding procedure:
1. 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
2. Please make sure your ExpressLRS tx module firmware is v3.x.x. And go to ExpressLRS.lu Afrom ??TOOLSnbsp;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 ??offnbsp;to ??onnbsp;or from ??onnbsp;to ??offbr>
Receiver LED status meanings:
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.
Bind successful

No RC Input
