This project is a compact STM32F411-based PCB intended for drone controller development. It brings together a microcontroller, motion and pressure sensors, satellite positioning, wireless communication, and external flash memory on a single board.

The goal is to provide an integrated hardware platform for exploring embedded programming, sensor processing, and drone control, while reducing the wiring required when using separate development modules.

The main hardware components are:

• STM32F411CEU6 microcontroller.

• ICM-42605 motion sensor.

• BMP280 barometric pressure sensor.

• L86-M33 GNSS positioning module.

• LoRa1276-C1 915 MHz wireless module.

• W25Q16JVSSIQ external flash memory with 16 Mbit capacity.

• AP7361C-33E voltage regulator providing a 3.3 V supply.

• USB-C connector, SWD programming/debug interface, UART connectors, and SPI test points.

The intended operating concept is to use the STM32F411 to process sensor measurements and positioning information. Firmware can be developed to estimate motion and orientation, use pressure measurements for relative altitude estimation, and exchange telemetry through the LoRa module. The external flash provides storage that can be assigned to configuration data or logging.

These are development objectives, and their implementation depends on the firmware and hardware validation. The manufacturing files alone do not demonstrate autonomous flight, stable flight control, or AI functionality.

The PCB has four copper layers and measures approximately 55 × 55 mm. The manufacturing files were exported from KiCad 9.0.0. The shared package includes Gerber layers, plated and non-plated drill files, a bill of materials, component placement data, and an IPC netlist.

The package documents the hardware for review and prototype development. Firmware, assembly verification, sensor calibration, communication testing, and flight-test results are not included. Further development and testing are required before treating the board as a validated flight controller.
