Flash Hobby Arthur 70A 32Bit 3-6S ESC

Features

Advanced Microprocessor: Equipped with a 32-bit ARM Cortex MCU STM32F051 operating at 48MHz, this ESC boasts a throttle resolution of 2048, providing outstanding anti-interference capabilities.
Built-in Sensor: The ESC includes a built-in sensor that can monitor temperature, output power, output current, and more. It is also programmable for customized protection settings.
Firmware Flexibility: This ESC supports the BLHELI_32 firmware, allowing for easy online firmware updates and configuration changes via the signal wire.
Current Meter: A built-in current meter provides real-time current indication on your OSD (On-Screen Display).
Customizable Settings: With a USB link, you can easily program throttle settings, including positive and negative modes, FPV 3D mode, motor speed, braking, PWM frequency, and inlet angle speed settings. It also features an onboard RGB LED for customizing colors and a beep function.
Adaptive Control System: Utilizing a self-adaption control system, this ESC can automatically work with various motors available in the market. It supports high-frequency PWM (up to 500Hz) and protocols such as oneshot 125, oneshot 42, Multishot, and Dshot 150/300/600/1200.
Optimized Multi-Axis Performance: Specifically optimized for multi-axis applications, this ESC provides smoother motor performance with excellent throttle response, high power output, and wide compatibility with multi-axis setups, fixed-wing aircraft, and helicopters.
Crosstalk Reduction: The twisted-pair signal wire design minimizes crosstalk within the copper wire during data transfer, contributing to improved flight stability.
Double Voltage Protection: The ESC’s MCU hardware, driver circuit, and Mosfet are equipped with double voltage protection, enhancing overall reliability.
Efficient Cooling: The MOSFET is covered with an aluminum sheet for efficient cooling, ensuring stable and efficient operation.
Enhanced PCB Design: A 6-layer thickened PCB design reduces resistance, minimizes heat generation, and increases resistance to high currents. The optimized component layout results in a smaller, lighter, and easier-to-install ESC.
