Description

The Holybro Pixhawk 4 Mini Autopilot Flight Controller condenses the core FMU processor and memory resources of the full-size Pixhawk 4 into a miniaturized form factor. By eliminating typically unused interfaces, it achieves a compact 55x38mm footprint ideal for 250mm racing drones and other small autonomous platforms without sacrificing computational power.

Engineered for robust operation, it features an aluminum casing for optimal thermal performance and a wide operating temperature range from -40°C to 85°C. The board is pre-installed with the latest PX4 firmware and provides easy connectivity to commercial ESCs via its standard PWM outputs, enabling rapid integration into custom drone builds.

Key Features

  • High-Performance STM32F765 Core: Delivers the processing power required for complex autonomous flight algorithms and sensor fusion.
  • Optimized Mini Form Factor: Streamlined design retains essential I/O while fitting into space-constrained mini drone frames.
  • Robust Aluminum Enclosure: Provides excellent EMI shielding and heat dissipation for reliable operation in varied environments.
  • Pre-Configured PX4 Firmware: Ships ready for use with the open-source PX4 autopilot stack, supporting a wide range of flight modes.
  • Flexible Power & I/O: Accepts 4.75-5.5V input, provides regulated 5V output, and includes 4 input / 8 output PWM channels for peripheral control.
  • Wide Temperature Tolerance: Certified for operation from -40°C to 85°C, suitable for extreme climatic conditions.

Applications

  • 250mm and smaller FPV racing drone builds requiring autonomous flight capabilities.
  • Compact survey and mapping drones where space and weight are critical constraints.
  • Educational and research platforms for PX4 autopilot development on miniaturized airframes.
  • Lightweight cargo or delivery drone prototypes operating under 5-inch propellor size.

Frequently Asked Questions

Does the Holybro Pixhawk 4 Mini include a GPS module?

No, the Pixhawk 4 Mini is sold as a standalone flight controller unit and does not include a GPS module. For autonomous navigation functions like position hold or return-to-home, you will need to connect an external GPS+Compass module, such as the Holybro M8N or M9N, to one of its serial ports.

What is the input voltage range for the Pixhawk 4 Mini?

The flight controller accepts a input voltage range of 4.75V to 5.5V. This is typically supplied via a 5V BEC from your ESC or a separate regulated power source. It provides a regulated output voltage of 4.75V to 5.25V for powering peripherals like receivers or telemetry radios.

Can I use this with Betaflight or is it only for PX4?

The Pixhawk 4 Mini is designed and pre-flashed specifically for the PX4 autopilot firmware stack, which is optimized for autonomous and robotic applications. It is not compatible with Betaflight, which is tailored for acro and rate-mode FPV flying. For PX4-based builds like mapping drones, rovers, or VTOL aircraft, it is an ideal choice.

What is the physical size and mounting pattern?

The board measures 55mm in length and 38mm in width, with a weight of 37.2 grams. The specific mounting hole pattern is not listed in the standard specs, but it is designed to fit within common mini drone frames. You should verify the hole spacing against your frame's FC mounting pattern before purchase.
