Drone Control Board Development

Brief description:

• We developed a versatile drone control solution using an STM32F4 microcontroller and the Pixhawk flight control system. The primary communication channel leverages UART for sending user commands, ensuring a reliable and low-latency control interface. To provide system redundancy, we also implemented PPM (Pulse Position Modulation) control, using two general purpose timers for signal generation, guaranteeing continued operation in case of primary channel failure.

Key features

• STM32F4:

  • High-performance microcontroller delivering real-time response and efficient data handling.

• Pixhawk Integration:

  • Robust flight control system receiving commands over UART, ensuring stable and accurate drone maneuvering.

• Redundancy & Fallback:

  Backup PPM control with a chain of two UART timers, maintaining drone control even if the primary communication path is compromised.

This solution highlights our expertise in delivering state-of-the-art, secure, and user-friendly authentication devices that support modern password-less workflows and enhance overall digital security.
