What we say...
Sure it's 2 separate boards, but this is the proven and reliable stack for all 85 and 95 builds. There are AIO boards out there that do work, but the reliability can be spotty, and the performance on 4s just not there. We recommend going this route until we find an AIO that we find acceptable because 4s is definitely the way to go for these 85/95 builds.
This is also the proven FC where you can trigger REC via a switch (check out the guide: https://docs.google.com/document/d/1pr1Keda1WNXBnsf7Zf1-mdbudHe9SXlXs_ossa-2c9c/edit?usp=sharing
What they say...
INCLUDES VTX WIRING PIGTAIL!
For those of you that want to upgrade your brushless whoop to use a TBS Unify Nano VTX, we have included the VTX wiring pigtail. You're welcome.
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!
Know more about BLHeli_32 ESC from Oscarliang's blog.
Check out Joshua Bardwell's video to know every detail of BLHeli_32

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
Here is the connection diagram with Frsky XM receiver or XM+ receiver
