NewBeeDrone Hummingbird 305 4in1 ESC 80A 3-8S AM32 30x30
by NewBeeDrone

The NewBeeDrone Hummingbird 305 4in1 ESC 80A 3-8S AM32 (30.5x30.5mm) is an industrial-grade electronic speed controller engineered for high-power 5-inch, 7-inch, and 10-inch FPV drones. Built on a 6-layer, 3oz heavy-copper PCB featuring blind via gold plating, this ESC delivers extreme electrical conductivity and thermal heat dissipation under continuous high-current loads. It supports 3S to 8S LiPo input and handles up to 80A continuous per channel (for 10 seconds) and 100A burst output (for 3 seconds).

Powered by the AT32F421 MCU with integrated gate drivers running open-source 32-bit AM32 firmware, the Hummingbird 305 ESC provides smooth low-RPM startup, rapid throttle response, and customizable PWM switching frequencies. For maximum electrical protection, the board incorporates three massive onboard TVS diodes capable of absorbing over 1.5kW peak power surges, eliminating the need for external TVS protection boards. It also features factory nano-coating for environmental durability and corner-mounted pads for convenient external capacitor installation.

Key Features

• Heavy-Duty 80A Power Handling: Delivers 80A continuous (10 sec) and 100A burst (3 sec) per channel across 3S to 8S LiPo voltage ranges.

• 6-Layer 3oz Heavy-Copper PCB: Built with blind vias and gold plating for optimal current delivery, minimal voltage drop, and enhanced thermal dissipation.

• AT32F421 MCU with AM32 Firmware: Integrated gate drivers and 32-bit processing deliver clean motor commutation and rapid throttle response.

• Integrated 1.5kW+ TVS Surge Protection: Three onboard TVS diodes protect sensitive electronics against inductive voltage spikes without requiring external surge suppressor boards.

• Corner-Mounted Capacitor Pads: Dedicated corner pads streamline soldering external low-ESR capacitors for high-voltage 7-inch and 10-inch builds.

• Factory Protective Nano-Coating: Pre-applied protective coating shields components against moisture, debris, and wet landings.
