Pixhawk Baseboard v2 Ports
This baseboard is compatible with both Pixhawk 5X & 6X, and any flight controller that follows the Pixhawk Bus Standard.
The ports and pinout of the Pixhawk Baseboard v2A and v2B are identical. The only difference is the orientation of the header pins.
Refer to diagram below for location of pin1. All connectors are JST GH 1.25 mm Pitch unless noted otherwise.
The Pixhawk Baseboard v1 has been replaced by the v2A & V2B. See the Baseboard Changelog for difference.
