A major benefit is that the plugs have screw terminals, making attaching/detaching them to wires very convenient. The **male** connector is the **receptacle** on the board, and the **female** connector is the pluggable terminal block itself.

 The motor board's UART interface (an alternative to controlling it over USB) uses a fourth type: 4 pins, 3.81mm pitch. However, we don't currently make use of this feature in the kit.
 
+Note that the female connectors are **not** symmetrical, and the retaining clips on the top of the block are offset to the left slightly. If you are assembling cases that these connectors must be inserted into, you will need to take into account the orientation of pieces that may look interchangeable but in reality are not due to these keyed clips.
