FlySky FS-A8S 2.4G 8CH Mini Receiver Module Rev 2

Description The FlySky FS-A8S 2.4G 8CH Mini Receiver Module Rev 2 is designed for lightweight drone and RC aircraft applications where space and weight are critical. It operates using the AFHDS 2A (Automatic Frequency Hopping Digital System) protocol, which improves signal stability and reduces interference between multiple radio systems. This mini receiver supports multiple signal outputs including PPM, i-BUS, and SBUS, allowing easy connection to flight controllers such as Pixhawk, APM, Betaflight boards, and other RC control systems. With its ultra-compact design and lightweight structure, the FS-A8S is widely used in racing drones, micro quadcopters, and compact UAV builds. Key Features 2.4GHz AFHDS 2A digital communication protocol Supports PPM, i-BUS, and SBUS output signals Compact and lightweight receiver module Fast signal response with channel delay under 15 ms Compatible with FlySky transmitters such as FS-i4, FS-i6, FS-i6X, and TM8 Reliable frequency hopping technology for interference resistance Ideal for small drones and multirotor aircraft Specifications Specification Details Model FS-A8S Rev 2 Frequency 2.4 GHz Protocol AFHDS 2A Channels 8 CH (PPM) / up to 18 CH via i-BUS Operating Voltage 4.0 – 8.4 V Control Distance Up to ~300 m Signal Output PPM / i-BUS / SBUS Dimensions 20 × 14 × 5.3 mm Weight ~1.2 – 6 g The receiver uses 135 frequency bands within 2.4 GHz (2.408–2.475 GHz) to maintain stable communication and reduce signal interference.
