FlySky FS-i4X 2.4GHz 4CH AFHDS R/C Transmitter with FS-A6 Receiver Pinout Guide
The FlySky FS-i4X transmitter and FS-A6 receiver are popular components in the world of radio control (R/C) systems. Understanding the pinout of these devices is crucial for connecting them correctly and ensuring reliable operation. Here's a detailed pinout guide for the FS-A6 receiver:
FS-A6 Receiver Pinout:
The FS-A6 receiver has a total of 6 pins, arranged in a single row. Here's a point-by-point explanation of each pin:
1. VCC (Pin 1): This pin provides the power supply to the receiver, typically in the range of 4.5V to 6.5V. Connect this pin to a suitable power source, such as a battery or a voltage regulator.
2. GND (Pin 2): This pin is the ground connection for the receiver. Connect it to the ground of your power source and the rest of your circuit.
3. S.BUS (Pin 3): The S.BUS (Serial Bus) pin is used for transmitting and receiving data between the receiver and the connected devices, such as servos, ESCs, or other components. This pin supports the S.BUS protocol, which allows for the connection of multiple devices on a single bus.
4. CH3 (Pin 4): This pin provides a PWM (Pulse Width Modulation) output signal for Channel 3. You can connect this pin to a servo, ESC, or other devices that require a PWM input signal.
5. CH2 (Pin 5): This pin provides a PWM output signal for Channel 2. You can connect this pin to a servo, ESC, or other devices that require a PWM input signal.
6. CH1 (Pin 6): This pin provides a PWM output signal for Channel 1. You can connect this pin to a servo, ESC, or other devices that require a PWM input signal.
Connection Structure:
Here's a general connection structure to keep in mind when connecting the FS-A6 receiver to your devices:
Connect the VCC pin to a suitable power source (e.g., a battery or voltage regulator).
Connect the GND pin to the ground of your power source and the rest of your circuit.
Connect the S.BUS pin to the S.BUS input of your devices (e.g., servos, ESCs).
Connect the CH1, CH2, and CH3 pins to the corresponding input pins of your devices (e.g., servo signal pins, ESC signal pins).
Important Notes:
Ensure that the power supply to the receiver is within the recommended voltage range (4.5V to 6.5V) to avoid damage to the component.
Use appropriate connectors and wiring to connect the pins, taking care to avoid short circuits or misconnections.
Consult the datasheets and documentation for your specific devices to ensure correct pin connections and configuration.
By following this pinout guide and connection structure, you can successfully integrate the FlySky FS-i4X transmitter and FS-A6 receiver into your R/C system projects.
