After several months of research, the greatest combination of F405 4S Brushless Flight Controller with BLHeli_32 16A ESC has been released which totally supports 4S power with a steady performance. BLHeli_32 16A ESC is customized for Beta85X whoop drone. Meanwhile, Beta85X is the first micro drone with a BLHeli_32 ESC at present.
BLHeli_32 is the 3rd generation ESC firmware after BLHeli and BLHeli_S, which is written for ESC's that utilize 32-bit MCU. With the increase in processing power, faster input signals with lower latency and higher update rate would be possible in BLHeli_32, such as Dshot1200!

DIAGRAM FOR F405 4S FC
- F405 4S FC board has added extra 4 pluggable ports for ESC, VTX, RX and LED board, convenient installation and decreasing the dislocated PIN mounting.
- Using single N-channel MosFETs on ESC board, which has a lower inner resistance. It is dual MosFETs on the original BLHeli_32 ESC board. Current sensor included.
- BLHeli_32 ESC is soldering with 25V/220uf electrolytic capacitor, for reducing the defective rate caused by the instantaneous high voltage.
HOW TO ASSEMBLE FC & ESC
In order to be convenient for the installation and decrease the dislocated PIN mounting, we have added a port for ESC connection. Separate installation, in case the mutural vibration may interfere between FC and ESC.
HOW TO ASSEMBLE FC & LED BOARD
In order to be convenient for the installation, we have added a port for LED board connection.
RECOMMENDED RECEIVER CONNECTION
In order to be convenient for the installation, we have added a port for RX connection. All the ports are available on this board. So that you could connect any receiver you want on the board. For example.
- Frsky XM/XM+ Receiver
- Flysky Receiver
- TBS receiver
- DSMX receiver
