The SPEEDYBEE F405 WING Wires Board Front features a variety of pins for connecting peripherals. Below is the pinout description:

1. Powering the Board: Connect a 2S–8S LiPo battery to the VBAT pin. Ensure the voltage is within the 7V–36V range.
2. Connecting Peripherals:
   • Use the UART ports to connect GPS, telemetry modules, or receivers.
   • Connect FPV cameras and VTX modules to the 9V output for stable power.
   • Attach servos or ESCs to the PWM outputs for motor control.
3. Configuring the Board:
   • Use Betaflight Configurator to set up the flight controller.
   • Assign UART ports to specific peripherals in the configuration tool.
   • Calibrate the IMU and set up the OSD for telemetry display.
4. Mounting: Secure the board using M3 screws and ensure proper vibration isolation.

• Voltage Compatibility: Always verify the input voltage to avoid damaging the board.
• Peripheral Connections: Double-check the pinout to ensure correct wiring of peripherals.
• Firmware Updates: Keep the firmware updated via Betaflight Configurator for optimal performance.
• Heat Management: Ensure proper airflow around the board to prevent overheating during operation.

Although the SPEEDYBEE F405 WING is not typically used with an Arduino UNO, you can use an Arduino to send telemetry data to the board via UART. Below is an example:

#include <SoftwareSerial.h>

// Define RX and TX pins for SoftwareSerial
SoftwareSerial telemetrySerial(10, 11); // RX = pin 10, TX = pin 11

void setup() {
  // Initialize serial communication
  Serial.begin(9600); // Default serial monitor
  telemetrySerial.begin(9600); // UART communication with SPEEDYBEE F405

  // Print initialization message
  Serial.println("Arduino to SPEEDYBEE F405 telemetry example");
}

void loop() {
  // Send telemetry data to SPEEDYBEE F405
  telemetrySerial.println("Telemetry data from Arduino");

  // Check for incoming data from SPEEDYBEE F405
  if (telemetrySerial.available()) {
    String data = telemetrySerial.readString();
    Serial.println("Received from SPEEDYBEE: " + data);
  }

  delay(1000); // Delay for 1 second
}

1. Board Not Powering On:

   • Cause: Incorrect input voltage or loose connections.
   • Solution: Verify the battery voltage and ensure secure connections to the VBAT pin.

2. No Communication with Peripherals:

   • Cause: Incorrect UART configuration or wiring.
   • Solution: Check the Betaflight Configurator settings and verify the pin connections.

3. OSD Not Displaying:

   • Cause: Misconfigured OSD settings or incompatible FPV camera.
   • Solution: Reconfigure the OSD in Betaflight and ensure the camera is connected to the correct pins.

4. Overheating:

   • Cause: Insufficient airflow or excessive current draw.
   • Solution: Improve ventilation and ensure peripherals do not exceed the board's power limits.

• Use a multimeter to check voltage levels at the pins.
• Update the firmware to the latest version to resolve software-related issues.
• Refer to the official SPEEDYBEE documentation for advanced troubleshooting steps.
