4 in 1 ESC 50A 2-6s Mico Air Electronic Speed Controller Bluejay Firmware with Double Hole Spacing for FPV RC Drone

High Adaptability Voltage Input Support: Suitable for a wide range of voltage inputs from 4-6s, compatible with drones of different sizes and power specifications. From 3-inch mini drones to 7-inch or even larger drones, all can be perfectly matched.
BlueJay Firmware Implementation: Equipped with the latest version of BlueJay firmware, utilizing up to 48K of default PWM frequency to effectively reduce electrical noise interference with the IMU, significantly improving flight control positioning accuracy in navigation modes. BlueJay also features a user-friendly interface and easy parameter adjustments, greatly simplifying user operation. Additionally, the ESC is compatible with traditional BLS firmware.
High-Performance MOSFET Device: The use of 40V 165A RDS=1.1mR MOSFET devices is key to enhancing ESC performance. An RDS(ON) as low as 1.1mR means minimal internal resistance during current flow, not only reducing energy loss and increasing efficiency but also resulting in lower heat generation and better load-bearing capacity. Especially during long periods of high load, it significantly reduces failure rates and extends service life.
Wide Compatibility with Control Signal Protocols: Supports various control signal protocols including DShot150/300/600, as well as bidirectional Dshot and speed feedback functions, ensuring perfect compatibility with most mainstream open-source flight controllers on the market without compatibility concerns.
Exceptional Circuit Design: The ESC PCB features a 6-layer 2oz thickened copper foil design, not only providing strong overcurrent capability but also significantly improved heat dissipation. Even under long-term high-load conditions, it maintains stable performance and extends the lifespan.
Multi-Specification Fixed Mounting Hole Design: Provides M4 (30.5*30.5mm) and M3 (20*20mm) mounting hole specifications, offering flexible installation options for drone frames of different sizes, enhancing universality and flexibility.
