The BETAFPV Cube is a 2–4S all-in-one flight controller that combines the FC, a 30A 4-in-1 ESC and a serial ELRS 2.4GHz receiver on one board. It is designed for power upgrades on Pavo-series whoops and for digital HD VTX builds, with a barometer, 16MB blackbox and a 9V BEC for HD air units.

Compatibility
Video: digital HD only (DJI O4 / O4 Pro, Walksnail) - there is no analog OSD chip.
Battery: 2-4S on XT30. Not for 1S whoops - use the Matrix 1S boards there.
Radio: built-in ExpressLRS 2.4GHz - pair with an ELRS radio.
Cube or F4 2-3S AIO? The F4 2-3S 20A AIO is the 3S board; the Cube's 30A ESC is the one to pick for 4S with LAVA 1104 5500KV motors.
