Flight Controller F405-HDTE
Description
1. Product Summary
1.1. Product Description
The Matek Systems F405-HDTE is a high-performance flight controller designed for advanced FPV and professional UAV applications. Featuring the powerful STM32F405RGT6 MCU, precision ICM42688-P IMU, and SPL06-001 barometer, it supports a wide input voltage range up to 12S LiPo (60 V). The board integrates dual 8-pin connectors for 4-in-1 ESCs, a dedicated 6-pin HD connector for DJI or digital video systems, and extensive connectivity options with 12 PWM outputs and 6 UARTs. Compact yet robust, it is ideal for large multirotors, cinematic FPV rigs, and long-range UAV platforms.
1.2. Product Features
- MCU: STM32F405RGT6 ARM Cortex-M4, 168 MHz clock speed.
- IMU: ICM42688-P high-precision gyroscope and accelerometer.
- Barometer: SPL06-001 digital pressure sensor.
- Input Voltage: 9 V ~ 60 V (3S ~ 12S LiPo).
- BEC Outputs: 5 V @ 1.5 A; Vx (9 ~ 16 V @ 1–2 A, for servos or VTX).
- UART Ports: 6 × full UARTs + SoftSerial support.
- PWM Outputs: 12 channels (supports 8 motors + 3 servos).
- I²C Bus: 1 × I²C for external sensors and compass modules.
- ADC Inputs: 4 × ADC (VBAT, RSSI, Airspeed, external sensors).
- HD Connector: SH1.0 6-pin port for DJI Air Unit / HD VTX systems.
- ESC Interface: Dual SH1.0 8-pin connectors for 4-in-1 ESCs.
- OSD: AT7456E + DJI OSD compatible.
- Mounting Pattern: 30.5 × 30.5 mm (Ø4 mm holes).
- Dimensions: ≈ 36 × 36 × 5 mm; Weight: ≈ 7 g.
1.3. Applications
- Professional UAVs: Heavy-lift or industrial multi-rotor systems.
- Cinematic FPV: Digital HD setups with DJI Air Unit or Vista.
- Long-Range FPV: High-voltage aircraft requiring 12S support.
- Research & Development: Ideal for UAV prototyping and ArduPilot integration.

4. Integration & Usage Notes
- Supports firmware targets
MatekF405-TEandF405-HDTEon ArduPilot / INAV / Betaflight. - Use external current sensor (PDB or ESC) for accurate amp monitoring — no built-in current sensor.
- For DJI OSD compatibility, connect through the 6-pin HD port using the supplied cable.
- Voltage sensor calibration recommended (1 kΩ : 20 kΩ divider ratio).
- Note firmware DMA limitations on DShot outputs (S3, S5, S7 pins in older Betaflight versions).
- Mount on soft rubber pads to reduce vibration for IMU accuracy.
5. Environmental Conditions
Table 5-1. Environmental Ratings
| Operating Temperature | -20 °C ~ +80 °C |
| Storage Temperature | -40 °C ~ +90 °C |
| Humidity | 5 % ~ 95 % (non-condensing) |
6. Precautions
- Do not exceed 60 V input voltage on VBAT input.
- Verify polarity and ground connections before powering on.
- Ensure ESCs and servos are rated for the connected battery voltage.
- Keep IMU area isolated from heat and electromagnetic interference.
- Use external PDB for current measurement if telemetry is required.
