Avem is a lightweight open-source drone flight controller firmware for STM32F103, implementing quaternion/euler attitude estimation from an MPU6050 IMU and cascade PID control of brushless motors under FreeRTOS. It includes KiCad schematics and PCB layouts plus a Flask/pyserial host tool for PID tuning.

Use cases

• build a lightweight quadcopter flight controller
• learn how PID attitude control works on a drone
• flash STM32 firmware for a brushless drone
• tune drone PID parameters from a host computer
• study open-source flight controller hardware design
• read MPU6050 gyro and accelerometer data over I2C

When to choose

• you want a small, readable codebase to learn drone flight control
• you are building a custom STM32-based quadcopter with MPU6050
• you need open hardware schematics and PCB layouts for a flight controller

When to avoid

• you need GPS navigation or waypoint missions (unimplemented)
• you need Wi-Fi telemetry (ESP8266 support is incomplete)
• you want a production-grade flight stack like Betaflight or ArduPilot
• you need support for many sensors or flight controller boards
