● 22mm cutouts for FPV camera in your tight build

*Beta flight 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 Beta flight 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

Wiring Diagram

Note: When using both a receiver and an Air Unit (including a direct connection using a ribbon cable) on the F405 V3 flight controller, there is an issue. This arises because the built-in SBUS receiver on the Air Unit and the external receiver are both connected to the Rx2 pad(SBUS pad) on the flight controller. As a result, the external receiver cannot be recognized properly by the flight controller. To resolve this, it is necessary to disconnect the SBUS wire from the Air Unit or connect the external receiver to the Rx3 pad on the UART3 port.
It is known that SBUS receivers and part of the ELRS receivers conflict with the built-in receiver on the Air Unit in the F405 V3 flight controller. Even ELRS receiver has this issue, but TBS receiver will not affected by this issue.

[A]. Press and hold BOOT button and power the FC on at the same time will force the FC to enter DFU mode, this is for firmware flashing when the FC gets bricked.
[B]. When the FC is powered on and in standby mode, the BOOT button can be used to controller the LED strips connected to LED1-LED4 connectors on the bottom side. By default, short-press the BOOT button to cycle the LED displaying mode. Long-press the BOOT button to switch between SpeedyBee-LED mode and BF-LED mode. Under BF-LED mode, all the LED1-LED4 strips will be controlled by Betaflight firmware.

And packaged with more useful features
● Built-in barometer for accurate height calculation
● SD Card slot can support up to 4GB Blackbox data*
● Dedicated DJI Air Unit connector for a quick digital build
● 9V 2A + 5V 2A individual BECs
● 4 x UARTs for your receiver + VTX + camera + GPS.
● Power your GPS with a USB cable – no battery needed.
No extra heat, no worries.
● 22mm cutouts for FPV camera in your tight build

*Beta flight 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 Beta flight 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.

Wiring Diagram

Note: When using both a receiver and an Air Unit (including a direct connection using a ribbon cable) on the F405 V3 flight controller, there is an issue. This arises because the built-in SBUS receiver on the Air Unit and the external receiver are both connected to the Rx2 pad(SBUS pad) on the flight controller. As a result, the external receiver cannot be recognized properly by the flight controller. To resolve this, it is necessary to disconnect the SBUS wire from the Air Unit or connect the external receiver to the Rx3 pad on the UART3 port.
It is known that SBUS receivers and part of the ELRS receivers conflict with the built-in receiver on the Air Unit in the F405 V3 flight controller. Even ELRS receiver has this issue, but TBS receiver will not affected by this issue.

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), 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.
