Product Description

The GEPRC SPAN F722-BT-HD v2 Stack is a premium electronics suite designed specifically for high-end digital FPV builds (like the MARK5 you looked at earlier). The "BT" in the name stands for Bluetooth, allowing you to tune your drone wirelessly from your phone—a lifesaver when you're in the field without a laptop.

Wireless Bluetooth Integration: No more carrying USB cables to the field. With the built-in Bluetooth module, you can connect your smartphone to the stack and adjust Betaflight settings, rates, and motor directions instantly.
Optimized for Digital HD: The "HD" version includes a dedicated 9V/2A BEC and a direct plug-and-play port for the DJI O3 Air Unit or Caddx Vista. This ensures your video transmitter gets clean, consistent power without the risk of voltage spikes.
High-Performance 50A ESC: The G50A ESC uses the latest BLHeli_32 firmware, supporting telemetry, bi-directional DShot, and high PWM frequencies for smoother motor response and increased efficiency.
Stable Power Delivery: The stack is designed with large, high-quality capacitors and filtered power rails to minimize electrical noise in your video feed and improve gyro performance.

Technical Specifications:

MCU: STM32F722RET6
Gyro/IMU: 42688-P (High precision)
ESC: 50A BLHeli_32 (Supports 3-6S LiPo)
Bluetooth: Built-in (SpeedyBee App compatible)
OSD: Betaflight OSD with AT7456E chip
Blackbox: 16MB onboard Flash
BEC: 5V/3A and 9V/2A
Mounting Pattern: 30.5mm x 30.5mm (Standard)

The Pilot's Reality Check:

App Dependency: To use the Bluetooth feature, you’ll need the SpeedyBee App installed on your iOS or Android device. It is much more convenient than a laptop but requires your phone to have a decent charge!
Installation Tip: Ensure you use the included anti-vibration grommets. High-performance F7 chips are sensitive to motor noise, and "soft-mounting" the stack is essential for a smooth flight feel.

🤔 FAQ: Frequently Asked Questions

Is it truly "plug-and-play" with DJI?
Yes. The flight controller features a dedicated 6-pin port that connects directly to the DJI Air Unit or O3 Air Unit using the included cable. This provides a clean power supply and OSD data transfer without the need for manual soldering, which is a major "asjalik" convenience for clean builds.
What is the benefit of the 512MB SD Card?
Most flight controllers use a small "Flash" chip (typically 16MB or 32MB) for Blackbox logging. The SPAN v2 includes a massive 512MB onboard SD card. This allows you to log hours of high-frequency flight data—essential for fine-tuning PIDs or troubleshooting motor vibrations—without having to constantly clear the memory.
Does the Bluetooth work for flashing firmware?
No. The Bluetooth connection is designed for parameter tuning (PIDs, Rates, UART settings, and Betaflight configuration). For flashing new firmware to the FC or ESC, you must still use the physical Type-C USB port.
How robust is the ESC?
The stack includes the BL32 50A 96K ESC, which uses 32-bit architecture and can handle a continuous 50A (55A burst). The "96K" refers to the PWM frequency, which provides exceptionally smooth motor response and better efficiency, particularly for 5-inch freestyle drones like the Mark5.
Does it have a barometer for altitude hold?
No. The F722-BT-HD v2 is built for performance freestyle and racing, so it omits the barometer to save space and reduce complexity. If you need altitude hold, you would typically add an external GPS module with a barometer.
