Here is the HummingBird F4 Pro 1S: The second generation of the HummingBird F4 products. Compared to the 1st Generation, we changed the Gyro to Bosch BMI160 which is smaller and more reliable compared to the MPU6000. (It can’t use the same firmware target as the 1st Generation HummingBird F4 1S.) We also changed the camera plug to have a JST 4 pin (OSD Signal, BeeSign signal, 5V, GND) so now you can either use BeeSign Control or BeeSign OSD (more explanation of the BeeSign is down below.) Also, we upgraded the propeller to the newest Azi Quad Blade 31mm Super balance Prop. Last but not least, we also optimized the layout and increase the high current layout trace to handle more power.

BeeSign OSD uses Mark2 MCU to simulate an OSD chip. BeeSign OSD is used to communicate between the flight controller and the onboard VTX OSD (NewBeeDrone Mark 1,2,3 Series Video Transmitter). The BeeSign OSD protocol is a non-stop communication signal whereas the BeeSign Control is passive.
BeeSign Control: Compared to BeeSign OSD, the BeeSign Control is a lighter version that only sends signal during VTX setting changes. Using BeeSign Control, the OSD signal comes directly from the flight controller.
Although BeeSign requires a lot of information of the controller to go through one single wire, BeeSign OSD only needs a BeeSign signal wire, a GND wire, and 5V power to reach the Mark2 VTX board.
Note: Beesign uses UART1 port. Do not use this port for other peripherals.
