The Motor Power Brick uses the MT3608 DC-DC Booster to scale the supply battery voltage to 6V for the Motor Brick or Servo Brick.
Parts list
| Type | Quantity |
|---|---|

Circuit
Solder the JST SM connector to the VIN terminals of the booster.
Solder the two JST RCY connectors to the VOUT terminals of the booster.
Connect the booster to the Battery Brick via the newly soldered JST SM connector.
Using a multimeter, measure the voltage on VOUT. At the same time, turn the screw on the potentiometer with a small screwdriver until the output voltage is around 6V.
Enclosure
Print out the enclosure parts on a 3D printer.
Sit the booster on the bottom piece, and arrange the wires in the grooves. Optionally secure the wires with a small amount of hot glue.
Mount the top piece with 4 x M2 screws.
Line up two 3x1 brickbases on a faceplate, five rows apart. Surround the brickbases with a few other bricks to assist in alignment.
Add two drops of superglue on each brickbase and mount the module. Press and hold for 60s.
