2. ASSEMBLY AND INSTALLATION
1. Connect both the motors to the corresponding sockets.
2. You can influence the power supply with the pin header:
If you want the motors to receive their power from the Raspberry Pi,
connect the two le-hand pins, marked on the following picture,
with the enclosed "jumpers":
3. However, if you want to supply an external power source, you can
install it on the two right pins, marked on the following picture:

4. Stepper motors are controlled by alternately supplying the individual
steps of the motor with power. The required pins for the steps of the
individual motors is shown in the following wiring overview:
