Our Regulated Electrical System provides a convenient way to power your projects. It's pretty simple: a battery holder, an on/off switch, and a 5 volt 3 amp BEC to provide regulated power.
The BEC is powerful enough to drive several standard servos or a dozen or more mini servos (as it does in our Vorpal The Hexapod project!)
You get four different choices for the battery holder:
- Two 18650 LI-ON batteries
- Six AA batteries
- Six AAA batteries
- No battery holder, just a male JST connector. This would allow you to connect a battery pack that uses a female JST.
The switch is rectangular with a 9x13mm size. We recommend making the hole 10x14mm if you are creating a 3D printed housing.
The circuit is shown in this diagram. Note that the actual battery holder would be whichever one you specified.
