Agree, except with the X2 that is not a V1 “Pixhawk” : different from factor, different connectors, impossible to identify which port is where (while it is clearly marked and visible on a Pixhawk). This does not make it a practical substitute to interface all of the components and cables made for the so-called original Pixhawk (telemetry units, GPS/Compass units, etc). Further X2 does not behave electrically like a Pixhawk, iot is not a 100% implementation of the electronics/electrical schematics.
I would hope for a Pixhawk like board that I could buy to support developers. Maybe an idea to pursue that could bring them some money ?
