Navigator Flight Controller Set

The Navigator is an expansion board that plugs into the Raspberry Pi 4 and turns it into a fully-featured flight controller, ready to power ROVs, USVs, drones, ground vehicles, and just about anything that moves!

At its core, the Navigator is a collection of inputs and outputs. It has inputs from onboard sensors, outputs to servos or speed controllers, and expansions ports that can be connected to external devices.

Onboard, the Navigator has:

  • 6-axis IMU with accelerometers and gyroscopes for orientation
  • Dual three-axis magnetometers for compass heading
  • Barometer for altitude in air
  • 16 servo PWM channel outputs
  • Current and voltage ADC inputs
  • Built-in leak detection for 2 probes
  • RC receiver input (SBUS)
  • RGB status LED

Additionally, the Navigator has expansion connectors available, all of which follow the Blue Robotics Connector Standard and are compatible with most industry autopilot accessories. It has the following expansion ports:

  • 4 serial ports
  • 2 I2C ports
  • 2 16-bit analog-to-digital converter (ADC) ports
  • External LED port compatible with Neopixel RGB LEDs

In addition, the Navigator has a number of important features that are worth highlighting:

  • Dual power inputs with automatic power switching for redundancy
  • 3.3V logic on all ports
  • 5V tolerance on serial ports
