1. BETAFPV Upgraded F405 V2 FC 4S Brushless Flight Controller and BLHeli_32 16A ESC OSD Smart Audio No Receiver with XT30 Cable for Brushless Beta85X Micro Quadcopter Cine Whoop Drone

Feature

This combo of F4 FC with BLHeli_32 16A ESC built-in BetaFlight OSD is customized for Cine whoop drone Beta85X. Please note: When you connect the receiver to this FC, don't forget to plug the battery, otherwise the receiver will have no power to work at all.
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.
Firmware version of F4 FC is Betaflight OMNIBUSF4SD (OBSD), built-in BetaFlight OSD (STM32 controls OSD chip over SPI in DMA mode). Support TBS micro receiver with TX02, RX02 ports. RSSI ports is available.
This ESC support BLHeli_32 suite pass-through ready, Support PPM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300, Dshot600, Dshot1200. It can fit motors with 1.5mm header pins connector like 1105,1103 motors etc, and you can use it work with 450mAh 3S battery or 450mAh 4S battery.
Please note this F4 2S-4S FC is built without receiver, all the ports are available on this board. So that you could connect any receiver you want on the board. Such as Frsky XM/XM+ Receiver, TBS receiver and DSMX receiver. Receiver Connection: https://betafpv.freshdesk.com/support/solutions/articles/27000049913-f4-2s-brushless-fc-esc

    Feature

    Built-in Current MeterThis F4 2-4S AIO FC V3 version has a built-in current sensor, you could get a more accurate current value without the virtual current meter
    Cautions when using 4s batteryThis F4 AIO FC can really support 4S battery. But please don't use motors with too high KV value or poor quality. No 0x0x/1102/1103 series motors could stand 4S power for the moment in the market
    Integrated FC with light weight Only weighs 5.6g integrated with a Betaflight MATEKF411 processor FC, Betaflight OSD and 2-4S 12A ESC which can support 4S battery for fast flying experience
    Supported ReceiverThe F4 2-4S AIO FC Brushless Flight Controller builted without receiver, please note it only Support Frsky XM/XM+ Receiver/ Futaba Receiver/ Flysky Receiver/ TBS Crossfire Receiver.

    4S1105 5000KV Motor

    Could the ESC on this AIO board support really 4S battery?
    Yes. But please pay more attention to the motors. Here are two situations that the motor will burn itself and then the ESC frequently.
    Situation 1:
    The motor's KV value is too high and could not stand the 4S power. For example, the BETAFPV 1105 6000KV motors could not stand the 4S power in aggressive flying. So we are working on a lower KV 1105 motor that could use with 4S battery. It will be released soon.
    Situation 2:
    A poor quality motor will result in the fire accident in 4S power. No 0x0x/1102/1103 motors could stand 4S power for the moment in the market. Please make sure your motors could support the 4S battery before any try.
