5. Setup

5.1. Physical Installation

1. Mounting: Securely mount the receiver in your RC model using double-sided tape or other appropriate methods. Ensure it is protected from vibrations and moisture.
2. Antenna Placement: Position the two antennas separately and vertically, ideally at a 90-degree angle to each other, to achieve optimal omnidirectional signal reception. Avoid placing antennas near carbon fiber or large metal objects that can block the signal.
3. Power Connection: Connect the receiver to a stable power source within the specified input voltage range (DC 3.5V~8.4V). Observe correct polarity (GND and VCC).
4. PWM Connections: Connect your servos or other PWM-controlled devices to the corresponding CH1-CH14 pins. Refer to your flight controller or model's manual for specific channel assignments.
5. CRSF/SBUS Connections: If using CRSF or SBUS protocol, connect the appropriate pins (e.g., GH2.0 4Pin port for CRSF) to your flight controller.
6. Voltage Detection: For battery voltage monitoring, connect the VBAT/6S pin to your battery's positive terminal (up to 6S).

5.2. Firmware Flashing (Optional)

The receiver comes pre-installed with ExpressLRS V3.3.0 firmware. If you need to update or change the firmware:

1. Connect the receiver to your computer using a Type-C USB cable.
2. Use the ExpressLRS Configurator software to select the appropriate firmware target for the SuperP receiver.
3. Follow the on-screen instructions in the Configurator to flash the desired firmware.

5.3. Binding Procedure

To establish communication between your transmitter and the SuperP receiver, a binding process is required. Ensure your transmitter is also running ExpressLRS firmware.

1. Power Cycle Method: Power on the receiver three times consecutively. Each time, wait for the RGB LED to flash rapidly, then power off. On the third power-up, the LED should flash slowly, indicating it is in binding mode.
2. Transmitter Binding: On your ExpressLRS-enabled transmitter, navigate to the ELRS LUA script or menu and select "Bind".
3. Confirmation: Once bound, the receiver's RGB LED will turn solid, indicating a successful connection.
4. Binding Phrase: Alternatively, if your transmitter and receiver share the same binding phrase configured in the ExpressLRS Configurator, they will bind automatically upon power-up.

6. Operating Instructions

6.1. Power On and Pre-Flight Check

1. Ensure all connections are secure and correct.
2. Power on your transmitter first, then power on your RC model with the receiver.
3. Observe the receiver's RGB LED. It should be solid, indicating a successful link with the transmitter.
4. Perform a range check and verify all control surfaces and functions respond correctly to transmitter inputs before flight or operation.

6.2. Failsafe Configuration

The failsafe function is critical for safety. It defines the receiver's behavior in case of signal loss.

1. Access the ExpressLRS LUA script on your transmitter.
2. Navigate to the Failsafe settings.
3. Configure the desired failsafe behavior (e.g., "Hold" to maintain last known positions, "Cut" to stop motors, or "Custom" for specific channel outputs).
4. Test the failsafe by powering off your transmitter while the model is powered on (ensure propellers are removed or motors are disarmed for safety). Verify the model reacts as configured.

6.3. Telemetry

The SuperP receiver supports telemetry, allowing you to monitor real-time data from your model on your transmitter screen.

• Ensure telemetry is enabled in your transmitter's ExpressLRS settings.
• The receiver will automatically transmit data such as RSSI, Link Quality, and potentially battery voltage if connected to the VBAT pin.
• Refer to your transmitter's manual for how to display and utilize telemetry data.

7. Maintenance

• Regular Inspection: Periodically check all wiring and connections for signs of wear, damage, or loose contacts.
• Antenna Condition: Ensure antennas are not bent, cut, or damaged. Replace if necessary.
• Cleaning: Keep the receiver free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning. Avoid using liquids.
• Firmware Updates: Check the official ExpressLRS website or BETA FPV resources for new firmware releases. Updating firmware can provide performance improvements, new features, and bug fixes.
• Storage: When not in use, store the receiver in a dry, cool environment, away from direct sunlight and extreme temperatures.

8. Troubleshooting

• Receiver LED Not Solid After Power On:
  • Ensure the receiver is correctly powered (3.5V~8.4V).
  • Verify the transmitter is powered on and transmitting.
  • Check if the receiver is bound to the transmitter. If not, perform the binding procedure (Section 5.3).
  • Confirm both transmitter and receiver are running compatible ExpressLRS firmware versions.
• No Control Response:
  • Ensure the receiver is successfully bound (solid LED).
  • Check all PWM/CRSF/SBUS connections between the receiver and flight controller/servos.
  • Verify channel mapping in your flight controller or model's configuration.
  • Check for any physical damage to the receiver or antennas.
• Short Range or Signal Loss:
  • Inspect antennas for damage or improper placement. Ensure they are positioned optimally (separated and vertical).
  • Avoid placing the receiver or antennas near noisy electronic components (ESCs, motors, video transmitters).
  • Check the transmitter's RF power setting.
  • Consider environmental factors (e.g., dense foliage, buildings, other 2.4GHz interference).
• Firmware Flashing Issues:
  • Ensure the correct COM port is selected in the ExpressLRS Configurator.
  • Try a different USB cable or USB port on your computer.
  • Ensure no other software is using the COM port.
