Wiring Diagrams

The prop can be powered by anything between 8.4v and 12v. If more than 12v is used, a heatsink or fan must be put on the 5v voltage regulator to prevent it from shutting down due to overheating. Using less than 8.4v may result in hardware glitches, and using less than 5v can damage the prop. The theoretical max voltage is 30v.

The buzzer circuit is controlled by a solid state relay with a max current draw of 1A. The relay connects whatever device is connected to the buzzer pins directly to the power source you use. 1A is enough to sound a larger noise making device, trigger a servo, or light an electronic fuse for a pyro display.
