Have just bitten the bullet and ordered a pixhawk.
I notice in the instructions is says 'APM power module-REQUIRED' and it appears to ship with one.
However I will be using it on my big octa and the 90A rated current of the power module will not be enough.
At the moment I am using a 180A attopilot on an APM2.6 (and its not that accurate) but the pixhawk has fancy connectors for the power module.
Is the 90A rating of the APM power module just a sensing limit and might it take way more before frying?
Is the power module really vital or can I power it from the servo rail?
Is there another option.
I am considering just using the APM power thing on half the motors and changing the settings to double the amps.
