Flashhobby XSD 7A BLHeli_S 1-2S Micro Brushless ESC, DShot600/300/150 PWM Oneshot Multishot

Overview

The Flashhobby XSD 7A is a micro brushless ESC for 1-2S LiPo input, running BLHeli_S firmware and supporting digital and analog throttle protocols including DShot and PWM. It is designed for multi-rotor applications where low weight and compact size are required.

Key Features

• BLHeli_S firmware; supports online firmware upgrade via signal cable
• Throttle signal support: DShot600/300/150, PWM, Oneshot125/42, Multishot, and Damped Mode (damped light/regenerative braking)
• Siliconlabs EFM8BB21F16G (QFN-20) MCU, up to 50 MHz operating frequency
• Dedicated high-speed drive IC for smoother startup; supports up to 500,000 rpm
• Supports pulse width input (1-2 ms) and automatic throttle signal detection
• Twisted-pair silicone signal cable to help reduce signal transmission interference
• Compatible parameter setup workflow via BLHeli configuration when used with CleanFlight or BetaFlight flight controllers
