SpeedyBee F405 V4 BLS 60A 3-6S 30x30mm Stack Flight Controller FC ESC for FPV Drones DJI Vista Link Air Unit O3 - ESC

FC Specifications:
Product Name: SpeedyBee F405 V4  Flight Controller
MCU: STM32F405
IMU(Gyro): ICM42688P
USB Port Type: Type-C
Barometer: Built-in
OSD Chip: AT7456E chip
BLE Bluetooth: Supported.
DJI Air Unit Connection Way: Two ways supported: 6-pin connector or direct soldering.
6-pin DJI Air Unit Plug: Supported. Completely compatible with DJI O3/RunCam Link/Caddx Vista/DJI Air Unit V1, no wire is needed to be changed.
Blackbox MicroSD Card Slot: *Betaflight firmware requires the type of the microSD card to be either Standard (SDSC) or High capacity (SDHC) under 32GB, so extended capacity cards (SDXC) are not supported(Many high-speed U3 cards are SDXC). Also the microSD card MUST be formatted with the FAT16 or FAT32 (recommended) format, you could use any SD card less than 32GB, but the Betaflight can only recognize 4GB maximum. We suggest you use this 3rd party formatting tool and choose 'Overwrite format' then format your card.
Current Sensor Input: Supported. For SpeedyBee BLS 55A ESC, please set scale = 400 and Offset=0.
