Optional Upgrade #2:
Power your electronics using Create’s internal battery
Connect a 5V UBEC (Buck) Converter to the dust bin electrical contacts and use power from
your Create 2 internal battery to power your electronics.
Shopping List:
• UBEC DC/ DC Step-Down (Buck) Converter – 5V @ 3A Output (Ex. Adafruit 1385)
• Inductor 2.2mH 500mA
Examples:
à
Abraco Corporation AIAP-03-222-K
à
Vishay Dale IHD3EB222L
à
Bourns Inc. 5900-222-RC
Instructions:
1) Instead of attaching the battery holder wires to the amplifier module, cut off the
connector on the output.
2) of the UBEC, strip the insulation off the wires, and screw the UBEC output wires to the
power terminals on the amplifier module.
3) Solder the red UBEC input wire to the red vacuum motor wire (the left vacuum bin
contact).
4) Solder one lead of the inductor to the black vacuum motor wire (the right vacuum bin
contact).
5) Solder the black UBEC input wire to the other lead of the inductor.
6) Use hot glue to secure the inductor somewhere in the bin so it doesn’t pull on the wires.
7) Plug the bin into the robot and command the robot to drive to apply power to the
bin contacts (either by pressing Clean to start a mission or using the Open Interface
command Motor – 138).
Now your electronics are powered by Create’s internal battery!
