Crazybee F4 Pro
About
The Crazybee F4 Pro Flightcontroller is a re-design of a common Omnibus F4 FC. There are different models with an embedded RC radio receiver. The Crazybee F4 Pro has embedded four ESC's to drive 4x brushless motors as commonly found on small racing quadcopters like the Trashcan Trashcan
Features
- Built-in 6A(each) Blheli_S 4in1 ESC
- Built-in OSD SPI Control
- Built-in Current meter Max 28A
- Built-in 5V 1A Buck Boost with LC filter
- Built-in voltage measure
- BLHELI_S pass-through Ready
- Taillight LED Ready
Specifications
- MCU: STM32F411CEU6 (100MHZ, 512K FLASH)
- Sensor: MPU-6000(SPI connection)
- Board size: 28.5 * 28.5MM
- Power supply: 1-2S battery input (DC 3.5-8.7V) altenative PCB with 2s-4s exist
- Onboard 4in1 ESC MCU EFM8BB21
Variations
The Flightcontroller exists in four different PCB variations
- CrazyBeeF4FRPro for use with Frsky
- CrazyBeeF4DXPro for use with Spektrum
- CrazyBeeF4Pro Without receiver
- CrazyBeeF4FSPro with Nordic chip for Flysky
Issues
Spiking power on the board when plugging in a 2s battery could lead to a broken board on the original design. To preven this from happening as add a capacitor to the battery lead. This capacitor should have an ESR lower than 0.2ohm and have a capacitance of 100uF or higher. A Rubycon ZLG/ZLH series and Samyoung NXB series.

Binding
To bind with your TX follow these steps
1. Connect battery 1. Pres an hold the bind button for about 2 seconds until the LED lits continuous 1. Enter the bind mode via your transmitter menu or bind button 1. The LED starts blinking as soon as binding was successful 1. Disconnect, then connect battery again, start flying
Debug connection
Per default the CrazyBee F4 Pro has no debug pin like SWD broken out to a connector or solderpad. One has to solder a tiny wire directly to the MCU. Like this:

Powering the Board
Depending on the board version. Two solder points. For v1s and 2s can be used
Schematic
At the moment there is no schematic since the design is not shared sadly by de original manufacturer of the PCB. However the current boardfile explains a bit of which pin goes where.

Connecting
The signal control pin where the LED strip on the backside is connected can be used as a PPM signal input. the VCC and GND can come from the main PCB.
