Introduction

Raspy UAV project is a quad-copter drone based on low-cost hardware components. Specifically, Raspberry Pi2 board, NAVIO operating system and the following:

  • MPU9250 Inertial Sensor and compass
  • MS5611 barometer
  • PCA9685 PWM generator (Adafruit 16-Channel 12-bit PWM/Servo Driver)
  • PIC18FJ11 for the RC input, battery and sonar monitor (see RaspySensorBoard repo)
  • uBLOX M8N GPS module via SPI

Communication between Raspberry and sensor board is based on I2C protocol where Raspberry acts as master and the uC as slave. Data acquisition occurs periodically at a rate high enough to guarantee safe control of the aircraft.
