Raspberry Pi implementation should be connected to A4988, DRV8825 or any other
stepper motor drivers with DIR and STEP pin inputs.
Default config is created for Raspberry Pi 2-3 and this wiring diagram:

gpio22 - heat bed
gpio27 - heater 2(or fan)
gpio18 - heater 1
gpio17 - not connected
gpio15 - not connected
gpio4 - not connected
gpio14 - not connected
gpio3 - i2c scl for ads1115
gpio2 - i2c sda for ads1115
ads1115 ch0 - heater 2(or not connected)
ads1115 ch1 - bed
ads1115 ch2 - heater 1
ads1115 ch3 - not connected
So having Raspberry Pi connected this way, there is no need to configure
pin map for project.
