C8T6 Blue-Pill Flight Controller is a custom flight controller built for an X-axis quadcopter using the STM32F103C8T6 (Blue Pill), a 32-bit ARM Cortex-M3 microcontroller. It's paired with the MPU6050 sensor, which combines a 3-axis accelerometer and 3-axis gyroscope to provide real-time data on orientation, acceleration, and angular velocity—essential for stable flight control.

The schematic and PCB were designed in EasyEDA and manufactured by LionCircuits. The board is optimized for clean signal routing and compact layout, enabling reliable performance in a compact drone setup. This project blends embedded systems, sensor integration, and PCB design into a complete UAV-ready solution.
