The manufacturer may make revision changes to their product, changing their voltage regulators and components. You should therefore always follow the instructions that came with your product.
When you receive your board, it is a good idea to check the output voltage levels with a digital meter to make sure that it is operating correctly and providing the correct voltage levels. You should get exactly 3.3 V and 5 V at the outputs. Although the manual states the maximum input voltage to be 12 V, it is better to keep to the low range such as 6.5 V.
You should thoroughly check your breadboard project circuit, and double check all the voltages before you connect it to anything else.
