Pixhawk 2

The Pixhawk 2 autopilot is a flexible autopilot intended primarily for manufacturers of commercial systems. It is based on the Pixhawk-project FMUv3 open hardware design and runs PX4 on the NuttX OS.

The controller is designed to be used with a domain-specific carrier board in order to reduce the wiring, improve reliability, and ease of assembly. For example, a carrier board for a commercial inspection vehicle might include connections for a companion computer, while a carrier board for a racer could includes ESCs form the frame of the vehicle.

Issues

The UAVCAN port labelled CAN1 does not work

At time of writing (October 2017) the CAN1 and CAN2 silk screen on the Pixhawk 2.1 is flipped (CAN1 is CAN2 and vice versa). The CAN2 port (labeled as CAN1) is not functional as it requires an external transceiver. The CAN1 port (labeled as CAN2) should be used as it has the transceiver built in.
