Flight Controller F411-WTE
Description
1. Product Summary
1.1. Product Description
The Matek Systems F411-WTE is a lightweight and efficient flight controller designed for fixed-wing aircraft and FPV wings. It features the STM32F411CEU6 microcontroller (100 MHz) with integrated ICM42688-P IMU and SPL06-001 barometer. With a compact form factor and built-in Power Distribution Board (PDB) and current sensor, the F411-WTE simplifies wiring and provides reliable power management for small to medium UAV platforms. Compatible with INAV firmware (Target: MATEKF411TE), this controller supports analog OSD, dual camera inputs, and adjustable BEC outputs — making it ideal for FPV wing pilots.
1.2. Product Features
- MCU: STM32F411CEU6, 100 MHz ARM Cortex-M4 processor.
- IMU Sensor: ICM42688-P high-precision gyro and accelerometer.
- Barometer: SPL06-001 digital air pressure sensor.
- Power Input: 6 V – 30 V (2S–6S LiPo) with surge protection.
- Current Sensor: 90 A continuous / 132 A peak with 0.3 mΩ shunt.
- OSD: Built-in analog video On-Screen Display (AT7456E).
- PDB: Integrated power distribution board with current sensing.
- Dual Camera Inputs: C1 / C2 video switching capability for FPV systems.
- BEC Outputs: 5 V (1.5 A), 6 V (5 A servo BEC).
- Firmware Compatibility: INAV (Target: MATEKF411TE).
- Compact Design: 31 × 26 × 16.5 mm, lightweight 10 g total weight.
1.3. Applications
- Fixed-Wing FPV Aircraft: Compact long-range planes and racing wings.
- VTOL Mini UAVs: Lightweight hybrid builds requiring integrated PDB and current sensing.
- Survey / Mapping Drones: Aircraft with modest current draw and precision control.
- Educational / Research Projects: Cost-effective flight controller for UAV training platforms.
