The WonderBorg has an Option connector, allowing even more advanced remodeling. The Option connector is on the underside of the WonderBorgrear end, and allows you to connect one external load such as a motor, or one external sensor such as a switch. To use this connector, you will need general knowledge of electrical circuits, a 2.54mm pitch, 4-pin connector (female) Morex type or other connector, and the ability to perform soldering. Care is needed when using the Option Connector: creating an inappropriate connection may damage the WonderBorg circuits.

Caution

Option Connector 2.54mm pitch, 4-pins may have sharp points.

Underside of WonderBorg

Option Connector 2.54mm pitch, 4-pins

Antenna

Leg

Fit the legs on the other side in the same way.

Use these parts if you prefer to make the assembly process as easy as possible.

Note: Turn the power ON before adjusting the angle of the legs.

Caution

If an inappropriate external circuit is connected to the Option Connector, this may result in damage to either or both the WonderBorg and the external circuit. Only connect an external circuit if you are fully aware of its specifications.

Option Connector

Use a 2.54mm pitch, 4-pin connector such as a Morex.

Load such as motor

select a load between 3 and 4.5 V, and not more than 500mA (This device can be switched ON for a given period of time using the "Option ON" command.)
