ZTW BX-F405 Flight Controller with ICM-42688-P Gyro, SPL06 Baro, 16MB Blackbox, Dual 5V/10V BEC and Type-C for 3-8S FPV Racing, Freestyle and Heavy-Lift Drones
F405 MCU with Betaflight for FPV
The BX-F405 is built around an STM32F405 processor running Betaflight, delivering stable flight performance and broad compatibility with the Betaflight configurator ecosystem. A proven platform for FPV racing, freestyle, and heavy-lift multirotor builds.
ICM-42688-P Gyro & SPL06 Barometer
The ICM-42688-P high-performance six-axis IMU provides clean, low-noise gyro data for precise flight control. The integrated SPL06 precision barometer enables altitude hold and GPS-assisted flight modes for long-range and autonomous missions.
16MB Blackbox & OSD with DJI HD Support
16MB onboard flash records blackbox logs for PID analysis and crash diagnostics. The OSD supports both analog and DJI HD digital VTX systems, with a reserved interface for direct DJI air unit connection.
Dual BEC: 5V/3A & 10V/3A
Two independent BEC outputs provide 5V/3A for receivers and peripherals, and 10V/3A dedicated to HD VTX systems — directly powering DJI and Walksnail air units without a separate voltage regulator.
3-8S Wide Voltage Input
Accepts 3S to 8S LiPo directly (11-36V), supporting high-voltage heavy-lift and long-endurance platforms as well as standard 4-6S FPV builds.
Type-C, 4 UARTs & Multi-Protocol Receiver
A side-mounted Type-C port provides easy configuration. Four hardware UARTs plus I2C support GPS, ELRS, CRSF, SBUS, IBUS, and DSM2/X receivers simultaneously — flexible enough for complex professional setups.
Compact 36.5mm Square, 10g
At 36.5×36.5×8mm and just 10g with standard 30.5mm M4 mounting, the BX-F405 stacks cleanly with ZTW BX 4-in-1 ESCs for a compact, lightweight flight stack.
