Brazil's electricity system is the same as that of the USA: 120 V; 60 Hz. Any electrical equipment you carry with you that operates at the higher (240v) rate will need to be dual-voltage (e.g. hair driers). A lot of electrical equipment (like video cameras, digital cameras, laptops) that operate on 12 volts via a product-specific adaptor will happily cope with dual voltage-check the adaptor and the device instructions to be sure.
You may need a socket adaptor. Most plugs in Brazil are the same as in the US; two flat prongs. Some have a third, circular prong for earth, and adapters can be sought for these too if the plug you want to connect to doesn't have the third (earth) prong socket.
More information coming soon.
