Decoding the FlySky FS-iA6B Receiver: A Comprehensive Pinout Guide

The FlySky FS-iA6B receiver is a 6-channel, 2.4GHz receiver widely used in radio-controlled (RC) applications, including drones, airplanes, and vehicles. Understanding its pinout configuration is crucial for proper setup and optimal performance.

FS-iA6B Receiver Pinout Configuration

The FS-iA6B receiver features multiple pins, each serving specific functions:

  1. Channel Outputs (CH1 – CH6): These pins correspond to the six channels and are used to connect servos or electronic speed controllers (ESCs).

  2. Battery Input (B/VCC): This pin is used to power the receiver. Connect the positive lead of your power source here, ensuring the voltage is within the specified range (4.0-6.5V DC).

  3. Ground (GND): This is the negative lead connection for your power source, completing the electrical circuit.

  4. i-BUS/SBUS/PPM Ports: Located on the top right of the receiver, these three pins are used for serial communication protocols. The pin configuration is as follows:

    • G (Ground): Connects to the ground of your flight controller (FC).

    • V+ (5V): Supplies power to the receiver from the FC.

    • Signal (i-BUS/SBUS/PPM): Transmits control signals between the receiver and the FC.

Connecting the FS-iA6B Receiver

To connect the FS-iA6B receiver to your RC device, follow these steps:

  1. Power Connection:

    • Connect the B/VCC pin to the positive lead of your power source.

    • Connect the GND pin to the negative lead.

  2. Channel Connections:

    • Connect your servos or ESCs to the corresponding channel pins (CH1 – CH6) based on your device’s configuration.
  1. Serial Communication (i-BUS/SBUS/PPM):

    • For i-BUS: Connect the signal pin to the i-BUS input on your FC.

    • For SBUS: Connect the signal pin to the SBUS input on your FC and select SBUS on your transmitter.

    • For PPM: Connect the signal pin to the PPM input on your FC.

Ensure that all connections are secure and that the polarity is correct to prevent potential damage.

Binding the Receiver to the Transmitter

Before operating your RC device, bind the FS-iA6B receiver to a compatible FlySky transmitter:

  1. Enter Binding Mode:

    • Press and hold the bind button on the receiver while powering it on. The LED indicator should start flashing, indicating it’s in binding mode.
  2. Initiate Binding on Transmitter:

    • Access the binding function on your FlySky transmitter as per its user manual.
  3. Complete Binding:

    • Once the transmitter confirms binding, release the bind button on the receiver. The LED should remain solid, indicating a successful bind.
