Pixhawk 2 Autopilot

Pixhawk 2 has been designed by the Pixhawk open hardware community in collaboration with 3D Robotics and was first released as the autopilot of the 3DR Solo. Although slated for a standalone release by 3DR, it eventually became only available two years later through an effort of Hex66 and ProfiCNC.

Prototype, back then with Molex Clickmate (final version has JST GH)
