Flashhobby Arthur 70A 32Bit ESC 3-6S BLHeli_32, DShot1200, 70A Cont/75A Burst, 21*42 mm

Overview

Flashhobby Arthur 70A 32Bit ESC is a BLHeli_32bit electronic speed controller (ESC) designed for 3-6S setups, supporting DShot1200 and multiple other throttle protocols. It uses a 32-bit ARM Cortex MCU (STM32F051, 48 MHz) and is built on a 6-layer thick PCB for lower resistance and improved durability.

Key Features

• BLHeli_32bit firmware; supports online configuration and firmware upgrade via signal wire
• Supports DShot1200 / 600 / 300 / 150, PWM, Oneshot125/42, Multishot, and Damped Mode
• 32-bit MCU: STM32F051 (48 MHz); throttle 2048 resolution ratio and anti-interference capability
• Built-in sensor for temperature, output power, output current; programmable protection
• Current Meter for OSD current indication
• Programmable via USB linker: bidirectional (positive/negative), two-way mode, FPV 3D mode, motor speed, braking, PWM frequency, timing settings, onboard RGB LED color, beep, etc.
• Self-adaption control system compatible with motors in the market; supports up to 500 Hz PWM
• Optimized for multi-axis response and throttle curve; also suitable for fixed-wing and helicopter applications
• Twisted-pair signal wire helps reduce crosstalk for more stable operation
• MCU hardware, driver circuit, and MOSFETs with double voltage protection
• Low internal resistance MOSFET process and dedicated MOS driver chip for efficiency
• MOSFET covered with aluminum sheet for cooling efficiency and stability

Specifications
