7. SMD Jumpers6. Connectors
If you want to use the motor driver’s enable
pin (#EN), solder J4 SMD jumper in ON
position. Otherwise leave it in the default
OFF position (connected to the ground).
There is a single SMD jumper (zero-ohm
resistor) J1 which is used to select between
3.3V or 5V power supplies. By default, it’s
soldered in the 3.3V position.
Two types of connectors are supplied in the
package: A B5B-XH-A connector, and two
screw terminals. Solder either one or the
other depending on the motor you want to
connect.
