Motor and Sensor Connector

The Cricket uses two-position connectors for the motor outputs and three-position connectors for the sensor inputs. These connectors are polarized, which means you can't insert them backward. (That is, unless you try really hard, and then they might break.)

The connector is made by a company called Hirose and it is their DF3 style. It's a very nice connector because it's reasonably robust, it's small, and it's fairly inexpensive. Further, one can buy pre-wired leads with a connector already crimped onto the wire.

To make a Cricket connection, you simply get the housing and then insert the leads with the pre-crimped connector.

Please note that the connector/lead assembly must go in the proper way. If it is inserted correctly, you will feel a tiny "click" as the connector locks itself into the housing. If it is inserted upside-down or side-ways, the connector won't lock and you can pull it out and try again.
