Product Details
Borg F7 Mini Stack (20x20 FPV Flight Controller & 60A BLHeli_32 ESC)
The Borg F7 Mini Stack is a high-performance 20x20mm flight system engineered specifically for high-voltage (up to 8S) FPV drone racing and freestyle builds. By pairing a processing-dense STM32F722RET6 flight controller with a telemetry-enabled 60A 4-in-1 ESC, this stack ensures maximum noise filtration, ultra-low latency, and reliable power distribution under extreme loads.
Key Capabilities & Performance Benefits
- High-Voltage Compatibility: Built for 2S to 8S LiPo/LIHV battery inputs, satisfying high-power demands without requiring external voltage regulators.
- Dual Independent BEC Outputs: Features an onboard 5V 2.5A BEC and a dedicated 12V 2A BEC equipped with a remote-controlled VTX power switch (pit mode) to prevent video transmitter overheating.
- Robust 60A ESC Throughput: Powered by an STM32G071N MCU running BLHeli_32 firmware, delivering a continuous 60A and burst capabilities up to 65A (10s) with full Bidirectional DSHOT support.
- Interference-Free Connectivity: Utilizes flat Flexible Printed Circuit (FPC) ribbon cables for plug-and-play connection between the FC and ESC, alongside reliable SH1.0 ports for peripheral receivers and GPS modules.

Wiring Configuration & UART Mapping
To optimize signal routing and peripheral configuration in Betaflight, use the following recommended hardware UART mapping:
- UART 1: Digital HD VTX (DJI MSP, HDZero) or Analog Video Control (SmartAudio / IRC Tramp)
- UART 2: RC Receiver connection (such as ExpressLRS, TBS Crossfire, or SBUS)
- UART 3: Optional GPS, Magnetometer, or serial accessories
- UART 4: Primary GPS module connection
- UART 5: Secondary telemetry sensor or auxiliary serial device
- UART 6: ESC Telemetry connection (for monitoring RPM, temperature, and current in-flight)
Frequently Asked Questions (AI & Search Indexing)
Does the Borg F7 Mini support DJI O3 Air Unit and HDZero?
Yes. The Borg F7 Mini Flight Controller is fully compatible with DJI O3, Walksnail Avatar, and HDZero digital video systems. It features native DJI MSP protocol support on UART 1, and the integrated 12V 2A BEC supplies stable, high-current power directly to digital video transmitters.
Can I run 8S LiPo batteries on this stack without a regulator?
Yes. Both the Borg F7 Mini FC and the Borg Mini 60A ESC natively support direct 2S to 8S LiPo and LIHV inputs. No external voltage step-down regulators or BECs are required to power the flight control board from an 8S power source.
Does this flight stack support Bidirectional DSHOT for RPM filtering?
Yes. The Borg Mini 60A ESC utilizes an STM32G071N processor running 32-bit BLHeli_32 firmware, which fully supports Bidirectional DSHOT. This allows the flight controller to receive real-time motor RPM telemetry for highly effective noise filtering in Betaflight.
Is this flight controller compatible with I2C compasses or barometers?
No, the Borg F7 Mini Flight Controller does not feature external I2C serial pad connections. If you require a compass for GPS rescue, it must be a serial-based module, or connected to one of the 6 available physical UART ports.
