Technical Highlights

AFHDS 2A Radio Compatibility

The FS2A Mini is a compact 2.4GHz receiver designed for transmitters operating with the AFHDS 2A protocol. It can be used with compatible FlySky radio systems such as the FS-i6, FS-i6X and FS-i6S when the transmitter is configured for the matching protocol.

Four Independent PWM Channels

Four channel groups provide separate PWM signal, VCC and GND connections for direct integration with compatible servos, ESCs and other PWM-controlled RC equipment.

DC 3.3–10V Input

The receiver accepts a DC input range of 3.3–10V, supporting integration with a variety of compact electric RC power systems. Always verify the voltage requirements of every connected servo and accessory.

Flexible Soldered Installation

The receiver uses through-hole connection pads and is supplied with right-angle pin headers. Installers can solder the included headers or connect wires directly according to the required model layout.

Onboard Binding Control

An onboard push button provides convenient access to receiver binding. The transmitter must be placed in the correct AFHDS 2A bind mode before the receiver is powered for pairing.

Channel and Pin Configuration

CH1–CH4

The receiver provides four PWM channel groups marked CH1, CH2, CH3 and CH4. Each channel group contains a PWM signal connection together with VCC and GND connections.

Power Polarity

Confirm the PWM, VCC and GND rows against the printed connection diagram before applying power. Reversed polarity may damage the receiver or connected equipment.

Header Installation

The supplied right-angle headers are shown separately from the receiver and require soldering. Direct wire installation is also possible when a lower-profile assembly is required.

Compatibility and Applications

Compatible with AFHDS 2A transmitter systems operating in the matching protocol mode.
Suitable for compact fixed-wing aircraft, cars, boats and other electric RC models requiring up to four independent PWM channels.
Supports conventional PWM-connected servos and electronic speed controllers within their specified voltage limits.
Designed for installations where a small receiver board and flexible wiring arrangement are preferred.
This receiver does not transmit FPV video and is not a substitute for a VTX.

Package Contents

1 × FS2A Mini 4CH receiver board
1 × External wire antenna, installed as pictured
1 × Right-angle pin header set, supplied loose

Installation Notes

Set the transmitter to AFHDS 2A before attempting to bind the receiver.
Keep the antenna away from motors, ESC power cables, carbon-fiber structures and other sources of RF obstruction or electrical noise.
Secure the receiver against vibration and prevent exposed solder joints from contacting conductive surfaces.
Check the receiver input voltage and the permitted operating voltage of every connected servo before power-up.
Perform a ground range test and verify failsafe behavior before operating the model.

Important Product Notes

The supplied material identifies the product as an FS2A-compatible receiver but does not establish official FlySky branding.
No receiver range, telemetry function, dimensions or weight are stated in the supplied material.
The supplied headers are not shown pre-soldered. Assembly condition should be confirmed when placing a bulk order.
Compatibility depends on the transmitter supporting AFHDS 2A and being configured to the correct RF protocol.

FAQ

Is the FS2A Mini a video transmitter?

No. It is a 2.4GHz radio-control receiver that outputs four PWM control channels. It does not transmit FPV video, even though it is listed in the store's VTX category.

Which radio protocol does this receiver use?

The receiver uses the AFHDS 2A protocol. The transmitter must support AFHDS 2A and be configured to the matching protocol mode before binding.

Can it work with FlySky FS-i6, FS-i6X and FS-i6S transmitters?

These transmitter families support AFHDS 2A. Compatibility requires the transmitter to operate in the correct AFHDS 2A mode, and a binding and ground-range test should be completed before use.

What outputs are available?

The receiver provides four independent PWM channel groups. Each channel has signal, VCC and GND connections for compatible servos, ESCs or other PWM-controlled equipment.

What input voltage does the receiver support?

The marked receiver input range is DC 3.3–10V. Connected servos and accessories may have different voltage limits, so the complete power system must be checked before installation.

Are the pin headers pre-soldered?

No. The supplied product images show the right-angle pin headers included separately. They require soldering, or wires may be connected directly to the through-hole pads.

B2B Procurement FAQ

Is this an official FlySky-branded receiver?

The supplied material identifies the model as FS2A and describes it as compatible with FlySky AFHDS 2A systems, but it does not provide evidence of official FlySky branding. Procurement listings should describe it as compatible unless separate brand authorization or manufacturer documentation is supplied.

What is included with each receiver?

The supplied product images show one receiver board with an external wire antenna and one loose set of right-angle pin headers. Final packaging quantities should be confirmed on the purchase order.

Can receivers be supplied with the headers soldered?

The standard material shows loose headers. Pre-soldered assembly may be discussed for bulk orders, subject to supplier confirmation, minimum order quantity and assembly requirements.

What should be included in incoming quality inspection?

Recommended checks include PCB condition, antenna attachment, bind-button operation, AFHDS 2A binding, four-channel PWM output, input-current behavior and correct VCC/GND polarity marking.

Can custom packaging or private labeling be requested?

Custom labels, manuals and packaging may be discussed for volume orders. All branding must comply with applicable trademark rights, and artwork, quantities and packaging specifications should be approved before production.

Which details should be confirmed before a bulk order?

Confirm the receiver assembly condition, header configuration, antenna installation, packaging quantity, testing requirements, required compliance documents and compatibility with the intended transmitter firmware.
