• 3× ADC (VBAT, Current, RSSI) for battery, current, and signal quality monitoring;
• 1× I2C for peripheral sensors or additional modules;
• 2× CAM for connecting cameras/FPV systems.

PDB Features (Power and Distribution)

• Operating Voltage: 6-30 V (2-6S LiPo);
• BEC 5V (for flight controller, receiver, camera, LED, GPS, etc.): output voltage 5V, continuous output current 1.5A, maximum 2A;
• BEC VBAT (for video transmitter, camera, etc.);
• BEC VX (for servos): output voltage 5V / 6V, continuous current 5A, maximum 6A;

• Current Sensor: 132A (90A continuous current).

Firmware and Compatibility — the controller is certified to work with iNAV and ArduPilot (target MATEKF405TE), providing flexibility in choosing an autopilot and control algorithms. The built-in OSD (AT7456E) simplifies integration with FPV equipment and displaying telemetry directly on the video feed. The 16 MB Blackbox allows for detailed flight logging for analysis and tuning.

Dimensions and Mounting

Thanks to its compact dimensions of 31×26×16.5 mm and mounting hole spacing of 22×22 mm (2 mm), the controller is easily integrated into small frames and chassis. A weight of only 10 g makes the board optimal for racing and mini-drones where weight minimization is crucial.

Package Contents

• Matek F405-WMN Flight Controller ×1 pc.;
• Matek Type-C Passive Buzzer ×1 pc.;
• JST-SH (6-pin) Cable ×1 pc.;
• Dupont 2.54 Pins ×2 pcs.

Practical Application — the Matek F405-WMN is suitable for FPV racing, mini-copters, and autopilot projects where weight, compactness, and a rich set of interfaces are important. The high-quality IMU ICM42688-P, built-in barometer SPL06-001, and support for two cameras ensure flight stability and precise positioning. Various BEC channels allow simultaneous powering of sensitive sensors, powerful video modules, and servos.
