Introduction

To power the electronics (Skycube board) a flat battery pack of 4 AAA is used. It can be connected to the molex connector on either sides of the board.

The parts needed are the following::

  • A flat battery pack, for 4 AAA batteries
  • A two-pin female molex connector
  • Two pins for the molex connector
  • Two pieces of heat shrink tube. Diameter: 2mm. Length: 10mm

Mounting

Step 1: Twist the wires

Twist the battery pack wires. It is optional, but it is recommended to do it. The resulting wire is more compact and resistent. In addition it will easier to wire the robot.

Step 2: Insert the heat shrink tubes

Insert the heat shrink tubes in both wires, as shown in the figure. Do not apply heat still.

Step 3: Apply solder in the wires ends

Use the soldering iron to apply solder in both wire ends. This will make easier to solder the male molex pins

Step 4: Apply solder in the molex male pins

Apply solder in the molex male pins. Just a little bit in the base is enough.

Step 5: Solder the pins to the wires

Solder the pins to the wires. Use a flat nose plier for holding the pin. Bring the wire near the pin and apply heat with the soldering iron. As both the pin and cable have solder their soldering will be done very easily.

Step 6: Apply heat to the shrink tubes

Place the heat shrink tubes in the lower half of each pin. Apply heat with the soldering iron. The shrink tubes will both prevent shortcircuits and make the union more resistent.

Step 7: Insert the wirtes into the female molex connector

Insert the pins into the female molex connector. ¡¡¡PAY ATTENTION TO THE POLARITY!!!. The red wire will be inserted in the hole 1. For inserting it is recommended to use a flat nose plier. If the pin does not enter smoothly use the pliers to smash a little bit the parts that cannot be inserted. When the pin is inserted correctly a slight click will be hear and the wire will not get when pulled.

Testings

  1. Connect the batteries to the Skycube power top connector.
  2. Turn on the board by means of the red switch. The red led will turn on.
  3. Connect the batteries pack to the power bottom connector. The red led will also turn on.
