Details
The BETAFPV Cube 2-4S Brushless Flight Controller is a 3-in-1 (3IN1) AIO specifically designed for the Pavo whoop series, combining an STM32G473CEU6 MCU (168MHz), a 2-4S 30A continuous-current Bluejay ESC, and an integrated Serial ELRS 2.4GHz receiver on a single board. The ESC uses 2oz copper thickness to improve thermal efficiency, increasing the continuous current rating from 20A on previous F405 models to 30A. It features an integrated ICM42605 gyro (8KHz), TCBP001TA barometer, and voltage/current sensor. Dual BEC outputs provide 9V @ 2A and 5V @ 3A. UART3 is assigned to the receiver by default, while UART4 is dedicated to the HD VTX (MSP + Displayport). UART3 can be freed by removing a resistor on the board. Two additional full-featured serial ports (UART1/UART2) are available for external CRSF/SBUS receivers, GPS, or other serial devices. Since the board is specifically designed for digital VTX systems, it does not include an integrated analog OSD chip. The ELRS receiver can be updated via WiFi or Betaflight passthrough (target: BETAFPV 2.4G AIO RX, ELRS 3.5.6). The ESC comes with Bluejay v0.19.2 48KHz firmware and supports DShot150/300/600 (target: C-X-70 48KHz.hex). The package includes a 220uF 25V capacitor, 30mm and 50mm connection cables for digital VTX, a 50mm XT30 cable, USB adapter and cable, vibration-damping balls, M2 nuts/screws, and heat-shrink tubing.
