Happymodel CrazybeeX 5in1 1-2S whoop FC

Happymodel is about to release CrazybeeX 5in1 AIO whoop flight controller. It is the first 5in1 AIO flight controller which could handle 2S. This flight controller is upgraded CrazybeeF4 Lite, includes the F4 MCU, OSD, 4in1 ESC, RX and VTX on one board and is capable of 1-2S battery input.  

The weight of the CrazybeeX 5in1 AIO flight controller is about 4.5 grams. 

You only need to add the camera (such as RunCam Nano 3)  and plug in the motors to make the complete build.

Happymodel CrazybeeX V1.0 connection pinout:

Noticed: RX1 can be used for IBUS/DSM2/DSMX signal imput from the external receiver. IR1 is the inverted signal of RX1 , used for SBUS input from external receiver.  RX1 and IR1 couldn’t be used at the same time.

Bind procedure:

  1. Make the on board receiver get into bind mode: For 3.5.7 version firmware Plug USB and then press the bind button for 1 second , the Red LED on the top of the flight controller will getting to be solid , this indicate the receiver is in bind mode; For 4.0.x version firmware Plug USB and then connect betaflight configurator and then move to CLI tab , type “bind_rx_spi” ,the Red LED on the top of the flight controller will getting to be solid , the onboard receiver is in bind mode; For 4.1.x or 4.2.x the bind code is “bind_rx”
  2. Make your transmitter get into bind mode . If bind is successful the red led will starting to blink.   The red LED wouldn’t blinking when binding with some new ACCESS firmware frsky radio, but the bind is actual successful , need to go to CLI command and type “save” to finish the binding .
