*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

Dimensions
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.
