Flight Controller F405-TE
1. Product Summary
1.1. Product Description
The Matek Systems F405-TE Flight Controller is a high-performance and feature-rich unit designed for fixed-wing, VTOL, and professional FPV UAV platforms. Powered by a STM32F405RGT6 168 MHz ARM Cortex-M4 processor, the board integrates a high-precision ICM42688-P IMU, SPL06-001 barometer, and a MicroSD slot for BlackBox logging. With six UART ports, eleven PWM outputs, and wide power input up to 36 V (8S LiPo), the F405-TE provides versatile connectivity, precise telemetry, and advanced flight control capability. Compatible with ArduPilot, INAV, and BetaFlight firmware.

4. Integration & Usage Notes
- Supports ArduPilot target
MatekF405-TEand INAV targetMATEKF405TE_SD. - DSHOT protocol is not supported on pins S3, S5, S7 (due to DMA conflict); use PWM or ONESHOT.
- Ensure current and voltage sensor scaling is set correctly in firmware (e.g., 66.7 A/V for 220 A sensor).
- BlackBox logging via MicroSD slot enables precise flight tuning and diagnostics.
- Compatible with 3S–8S LiPo input; verify power polarity before connection.
- Mount on vibration-isolated pads to ensure IMU accuracy and stability.

6. Precautions
- Observe correct polarity when connecting LiPo power to avoid damage.
- Do not exceed 8S battery voltage limit (36 V max).
- Ensure adequate airflow for heat dissipation under high load operation.
- Check IMU and barometer readings after mounting to verify proper alignment.
- Discontinued product — verify availability and authenticity before purchase.
