# OVERVIEW

The benefits of the Pixhawk Flight Control Unit (FC U) system include integrated multithreading, a Unix/Linux-like programming environment, complete ly new autopilot functions such as sophisticated scripting of missions and flight beha vior, and a custom PX4 driver layer ensuring tight timing across all processes. These advanced c apabilities ensure that there are no limitations to your autonomous vehicle. Pixhawk allows existing APM and PX4 operators to seamlessly transition to this system and lowers the barriers t o entry for new users to participate in the exciting world of autonomous vehicles. The flagship Pixhawk module will be accompanied by new peripheral options, including a digital airspeed sensor, support for an external multi-colo r LED indicator and an external magnetometer. All peripherals are automatically det ected and configured. Note: Pixhawk is a PPM-input autopilot, which means that it gets RC input from a single cable to the receiver, either via the PPM port, the Futab a S.BUS port, or the special satellite receiver port for Spektrum gear. Most modern RC receivers (a nd all those sold by 3D Robotics) allow for PPM output, but some, such as non-S.BUS Futaba rece ivers, do not. If your receiver does not support PPM output, please add a PPM encoder board option to your order below. Pixhawk includes:

# CONNECT

(Required) Connect the buzzer and safety switch.

(Optional) Connect a 3DR Radio to Pixhawk’s Telem port using the 6-wire cable provided with your 3DR Radio Kit to receive data and communicate with the autopilot in flight. (GPS or GPS+Compass required) Connect a 3DR GPS+Compass to provide the autopilot with positioning data during flight. This kit includes a 6-wire cable to connect the GPS ports. Connect the MAG to the I 2 C port using the 4-wire cable provided with the 3DR GPS+Compass. (Required) Connect the 3DR Power Module to the Power port using the 6-wire cable to direct power from your lithium polymer

(LiPo) battery to the autopilot.

(Optional) The I 2 C splitter expands the I 2 C port to allow up to four additional peripherals to connect to Pixhawk. Use the 4-wire cable to connect the I 2 C splitter and add a compass module, external LED, digital airspeed sensor, or other peripherals to your vehicle. 

# 2Connect the ground (-), power (+), and signal (S) wires to the RC pins using the provided 3-wire servo cable.

For a Spektrum DSM, DSM2, or DSM-X Satellite RC receiver, connect to the SPKT/DSM port.

Do not operate your vehicle without a complete understanding of the online instructions.Operating a powered vehicle of any kind can be a lot of fun, but it carries certain inherent risks. Regulations governing the use of powered vehicles, including aircraft, vary from locale to locale, even within the same country or district. It is your responsibility to ensure that you understand and comply with all local laws and regulations. Safety basics:

• Never operate the vehicle or software in a way that could be dangerous to you, other people, or property. • Always keep propeller arcs free of objects and body parts while the vehicle is live. • Keep in mind that software and hardware failures happen. Although we design our products to minimize

such issues, you should always operate with the understanding that a failure could occur at any time and without warning. Accordingly, you should take the appropriate precautions to minimize danger in case of product failure. • Never use the software or hardware for manned vehicles. • Always operate within local laws and regulations. • Do not operate the aircraft if you are under the age of 18. Additional safety information:

• Be sure to maintain safe distances between people and your aircraft. • Never operate your aircraft if your ability to do so with the utmost attention to safety is impaired in any

way. Do not operate your aircraft while tired, under the influence of drugs or alcohol, or otherwise unable to operate it with the highest attention to safety. • Environment conditions can change rapidly and can make operation difficult. If this occurs, land your aircraft

and discontinue use immediately. Do not operate your aircraft if operating conditions are not ideal. This includes, but is not limited to, rain, snow or excessive wind. • Always ensure the battery cable is disconnected from the aircraft until you are ready to fly, and ensure that

your batteries are fully charged prior to use. • Always turn on the transmitter and ensure the throttle stick is all the way down before connecting the

battery. • After landing, disarm your vehicle immediately and disconnect the battery cable. • Do not turn off the transmitter until after you have disconnected the battery. • Always remove the propellers while testing the motors. • When the battery is connected, always assume the vehicle is live and the motors are armed. • Do not attempt to fly longer than the battery’s safe capacity. • Do not operate the vehicle with excess weight attached. • Ensure that all vehicle components are well maintained before each flight. Ensure that components are

firmly attached and operating properly. • Replace any worn or damaged components before each flight. Never operate with any damaged or worn

components. • SAFETY IS THE FIRST PRIORITY. Take all precautions necessary to ensure your own safety as well as the

safety of other people and property.
