Matek F765-WING Flight Controller — Overview and Key Features

Name: Matek F765-WING Flight Controller
Manufacturer: Matek
Category: Drones & Quadcopters > Drone Components > Drone Spare Parts > Stacks (FC+ESC)

Brief Description

The Matek F765-WING is a modern flight controller for airplanes and winged platforms, combining the advantages of previous Matek F722-WING and F405-WING models, but featuring a significantly more powerful processor and expanded peripheral connectivity. The board is equipped with an STM32F765 MCU running at 216 MHz, 512Kb of RAM, and 2Mb of flash memory, ensuring stable operation of complex autopilot algorithms on iNAV or ArduPilot.

Technical Specifications

Main Components:

• MCU: STM32F765VIT6 (216MHz, 512Kb RAM, 2Mb Memory)
• Accelerometer/Gyroscope: MPU6000 (SPI1) and ICM20602 (SPI3)
• Barometer: BMP280 (I2C)
• OSD: AT7456E (SPI2)
• Blackbox: MicroSD card slot (SDIO)

Number of Outputs:

• Motors: 2
• Servos: 10
• PWM: 12
• UART: 7 (with built-in inversion)

Ports and Interfaces:

• 2 x I2C

• Voltage and current sensors

Mounting and Physical Parameters:

• Mounting: 30.5 x 30.5 mm (hole diameter 4 mm, with grommets 3 mm)
• Dimensions: 54 x 36 x 13 mm
• Weight: 26 g

PDB (Power Distribution Board)

Input and Protection:

• Input voltage range: 9 ~ 36V (3 ~ 8S LiPo) with TVS protection
• Current sensor: 132A, 3.3V ADC

BEC Outputs:

• 5V (for various modules, max. 3A)
• 9V/12V (for FPV equipment, max. 3A)
• Vx (for servos, adjustable voltage, max. 10A)
• 3.3V (for Baro/Compass modules, max. 200mA)

Firmware Compatibility

The controller supports iNAV and ArduPilot (ChiBiOS) firmware. Please note that some interface parameters and system behavior may differ depending on the chosen firmware, so the specifics of each platform should be considered during setup.

Usage Recommendations

Practical application recommendations (numbered in the list):

• 1. Use Camera-1 and Vsw functions by default for correct operation of dual-camera configurations.
• 2. When connecting two cameras, ensure both operate in the same video format: PAL or NTSC.
• 3. Be aware of port specifics: Rx5 is not supported, VB2 and CU2 are not active in INAV.
• 4. An additional BEC output can be connected to FC Vx and G pad to activate servos if the main and top BEC boards are not connected via Vbat/G/Vx.
• 5. Avoid loading OSD fonts via the MacOS INAV configurator; use the Windows version for this.

The Matek F765-WING is ideal for more complex aviation projects requiring a large number of servos, extended UART ports, and a reliable power supply with adjustable Vx for servos. Thanks to its two IMUs, SDIO BlackBox, and extensive peripheral connectivity, this stack will be the reliable heart of your aircraft or electronic winged device.

Note that some specifications may vary depending on the specific firmware platform: iNAV Flight or ArduPilot (ChiBiOS).
