Product overview
The BETAFPV F4 Brushless Flight Controller and ESC V2.0 (BLHeli_32) provides separate flight-control and motor-control boards for a micro whoop build. Its flight controller combines an STM32F405 processor, MPU6000 six-axis sensor and built-in BetaFlight OSD on a 26mm x 26mm board with a whoop mounting pattern. Four added pluggable ports accommodate the ESC, video transmitter, receiver and LED board. Receiver integration includes auto-inverted RX3/TX3 connections and TX01/RX01 support for FrSky F-Port and DSM2/DSMX, alongside buzzer solder pads and programmable LED support.
The ESC accepts 3-4S LiPo input and specifies 16A continuous current and 19A peak current, with control protocols extending through Dshot1200. Separate board installation addresses possible vibration interference between the FC and ESC. The combined package contains both boards, receiver and LED cables, screws and rubber dampers; FC-only and ESC-only options also exist. This is an electronics package rather than a complete aircraft or airframe kit. The recommended build uses a Beta85X frame, 1105 5000KV motors, a 450mAh 4S battery and 2-inch four-blade propellers. Its recommended motors specify 1.5mm connectors, while the ESC specifies 1.25mm connectors.
