Pixhawk 2

Pixhawk2 is the latest iteration of Pixhawk, which is an independent open-hardware project.
Pixhawk2 supports different kinds of airframes – helicopters, multicopters, planes, quadplanes, rovers and more!
An easy firmware update is all it takes to re-purpose your hardware into a different role.
Modular flight controller
Reduced integration complexity
Ample I/O for even the most complex airframes
All-in-one design with integrated FMU and IO processors
Vibration-damped IMU board
It comes 100% RTK GPS ready.
Multiple GPS capability is standard.

The Pixhawk 2 comes with ‘The Cube 2.1’ and features the following changes over the Solo version

  1. Heater added to the IMU’s
  2. New driver chip on the PWM out 1-8, which allows safer driving of OPTO ESC’s
  3. Fix added for the PPM / S.Bus input which improves signal quality.
  4. Move to MPU9250 to replace the MPU6000
  5. Removed some LEDs to improve Gyro noise.
