I am working to use RPI and Sense Hat to make a autopilot for a sailing boat.
I need to use PWM output to drive a motor to push and pull the rudder.
I use a MD10C board from Cytron to connect to the motor.
On RPI I have to connect the pin 12 ( GPIO 18 ) to the pwm input of the MD10C and pin 11 ( GPIO 17 ) for reverse mode.
My little problem is how to access to the pin!
I think about two solutions :
1/ solder from the butom of the RPI board ( not very elegant )
2/ solder inside the connecteur of the Sense Hat ( can't take it off after )
If you have any other idea...
