The SpeedyBee F405 V4 BLS 60A 30×30 FC & ESC Stack is an advanced flight control system designed for high-performance 8-inch and 10-inch FPV drones. It features an upgraded STM32F405 processor, built-in Bluetooth for wireless configuration, and a robust 60A 4-in-1 ESC with integrated heat sinks.

• • Wireless Configuration: Features a built-in Bluetooth module that allows pilots to configure both the flight controller and ESC settings via the SpeedyBee mobile app without needing a USB cable.
  • Enhanced Power Management: Equipped with a 60A continuous current rating per channel and a 320A peak load capacity. It includes a TVS protective diode to absorb voltage spikes and 20 high-quality SMD filtering capacitors.
  • DJI Air Unit Compatibility: Features a dedicated 6-pin plug-and-play connector compatible with DJI O3, RunCam Link, and Caddx Vista.
  • Onboard Monitoring: Includes a unique 4-level battery indicator on the side of the board for instant battery level checks without a separate LiPo checker.
  • Advanced Flight Stability: Utilizes the ICM42688P gyro powered by a dedicated MaxLinear LDO chip to reduce electrical interference for smoother flight.
  • Blackbox Logging: Supports microSD cards up to 32GB (SDHC only), allowing for extensive flight data logging.
