This is a Arduino-compatible autopilot board designed by Chris Anderson and Jordi Muñoz of DIY Drones.
This is a basic navigation-only autopilot that requires a GPS module and separate stabilization unit such as a FMA Co-Pilot to create a functioning Unmanned Aerial Vehicle (UAV). The hardware and software is all open source. The board comes with all the surface-mount parts already soldered, but requires the user to solder on connectors. Firmware is already loaded, but the autopilot software must be downloaded and loaded onto the board by the user. It can be programmed with the Arduino IDE. All details and instructions can be found at the project's home page.
We highly recommend the following items to accompany this product:
Other necessary elements, including aircraft recommendations, can be found at the project's home page. Note: The original build of boards (shipped before January 26th) had incorrect firmware loaded onto the ATtiny. This firmware made the ATtiny unable to put the ATmega into reset. If you happen to have received one of these older boards, and you are experiencing problems, you can re-flash the firmware on the ATtiny with an AVR programmer like the one in the related items below. The newest firmware can always be found here.
Features:
- Controller designed to be used with autonomous aircraft, car or boat. Stabilization unit required only for aircraft.
- Based on a 16MHz Atmega168 processor. Total onboard processing power aprox 24 MIPS.
- Built-in hardware fail-safe that uses a separate circuit (multiplexer chip and ATTiny processor) to transfer control from the RC system to the autopilot and back again. Includes ability to reboot the main processor in mid-flight.
- Multiple waypoints (limited only by memory)
- Comes with a 6-pin GPS connector for the 1Hz EM406 GPS module. Faster 5Hz GPS module, such as the Locosys 200031, are supported via an optional 3.3V daughter-board
- Has six spare analog inputs (with ADC on each) and six spare digital input/outputs to add additional sensors
- Supports addition of wireless downlink module for telemetry [code in development]
- Can be powered by either the RC receiver or a separate battery
- High-speed ASCII NMEA parser for compatibility with standard GPS modules at any baud rate
- Hardware-driven servo control, which means less processor overhead, tighter response and no jitters.
- Four RC-in channels (plus the autopilot on/off channel) can be processed by the autopilot. This allows the autopilot to read the initial throttle and rudder position when you switch to autonomous mode, so it can maintain speed and heading. The other two channels can be used for whatever you want, such as triggering a camera sequence or dropping an object. (Remember that the aileron and elevator channels are separately controlled by the FMA Co-Pilot)
- Status LEDs for power, fail-safe (on/off) and GPS (satellite lock)
