BetaFPV F4 2-3S 20A AIO FC V1 ELRS

The BetaFPV F4 2-3S 20A AIO FC V1 is a highly integrated flight controller engineered for digital HD micro builds. Designed to streamline wiring on cinewhoops like the Pavo Pico, it supports 2S to 3S LiPo power and features an onboard serial ExpressLRS 2.4GHz receiver for reliable, low-latency control without the bulk of an external module.

Key features

• Integrated serial ELRS 2.4GHz receiver avoids the UART bottleneck of older SPI receivers and allows seamless independent firmware updates.
• Built-in 20A continuous BLHeli_S ESC provides robust power delivery for 1103 to 1404 stator motors on 2S or 3S setups.
• Plug-and-play 6-pin socket delivers a direct, solder-free connection to DJI O3, Walksnail Avatar, or Caddx Vista digital VTX units.
• Features a standard 26x26mm whoop mounting pattern for drop-in compatibility with modern micro frames.
