Openlog Cleanflight Naze32 F3 Blackbox Flash Recorder Module

Openlog Cleanflight Naze32 F3 Blackbox Flash Recorder Module provides a specialized high-speed data logging solution for drone enthusiasts and engineers seeking to optimize flight performance. This compact serial logger captures comprehensive flight telemetry and system logs directly from flight controllers like the Naze32 or SP Racing F3. Consequently, it enables pilots to review “Blackbox” data to troubleshoot vibration issues, tune PID loops, and analyze flight dynamics with extreme precision. The module operates by receiving asynchronous serial data and writing it instantly to a microSD card. Furthermore, its lightweight design and low power consumption make it an ideal addition to racing quads where every gram matters. Therefore, you can achieve professional-grade flight analysis by integrating this reliable recording tool into your FPV system.

Key Features:

• High-Speed Logging: Supports high baud rates up to 115200bps, ensuring the device captures every nuance of the flight controller’s high-frequency data output.
• Cleanflight & Betaflight Compatibility: Optimized specifically for the Blackbox logging feature found in modern flight control firmware.
• MicroSD Support: Features an onboard slot that accommodates standard microSD cards (typically up to 32GB) for hours of continuous data storage.
• Plug-and-Play Serial Interface: Utilizes a simple UART connection, which simplifies the integration process with existing hardware.
• Automatic File Creation: The firmware creates a new log file every time the module powers up or receives a new data stream, preventing data overwrites.

Technical Specifications:

• Input Voltage: 3.3 V to 12 V (Recommended 5 V for most flight controllers)
• Operating Current: ≈ 2 mA to 5 mA (Idle), up to 20 mA to 50 mA (During active writing)

Commonly Used in:

• FPV Racing Drones: Recording gyro and motor data to identify mid-air oscillations and desync issues.
• Development Platforms: Connecting to Arduino or ESP32 projects that require long-term sensor data logging.
• UAV Research: Capturing GPS and altimeter data for post-flight path analysis.

Applications:

• PID Tuning: Providing the raw data necessary to visualize the relationship between setpoints and actual flight performance.
• Crash Analysis: Reviewing the final seconds of flight logs to determine the cause of hardware failures.
• Remote Sensing: Acts as a standalone serial logger for weather stations or remote telemetry units.

Equivalent Models:

• SparkFun OpenLog: The original open-source hardware design that serves as the foundation for this recorder.
• MicroSD Breakout Board: However, standard breakouts require the host MCU to handle the file system logic, unlike the self-managed Openlog.
• Integrated Onboard Flash: Some high-end F4/F7 controllers include onboard chips, but the Openlog offers significantly larger storage capacity via SD cards.
