So your package does not need to pay customs duties again when it arrives. If the payment amount is greater than 150 euros, AliExpress will not charge any additional fees when you pay, but when the package arrives at the customs, you need to pay VAT and customs duties on the package.)

SpeedyBee F405 V3 30x30 Flight Controller





USB Port Type




OSD Chip

AT7456E chip

BLE Bluetooth

Supported. Used for Flight Controller configuration

DJI Air Unit Connection Way

Two ways supported: 6-pin connector or direct soldering.

Blackbox MicroSD Card Slot

*Betaflight firmware requires the type of the microSD card to be

either Standard (SDSC) or High capacity (SDHC),so extended

capacity cards (SDXC) are not supported(Many high-speed U3

cards are SDXC). Also the card MUST be formatted with the

FAT16 or FAT32 (recommended) filesystems. So, 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. Also check out here for the recommended SD cards

or buy the tested cards from our store.
