Hence, if you wish to use it to its maximum capability you will need to remain in that range. This is a non-adjustable fixed power supply model, which is good enough for most applications.<\/li><li>Maximum output current to be 700 mA. However, it is probably better to use much lower voltages and current to be on the safe side in case you make a mistake on your breadboard circuit.<\/li><li>With 9V battery snap power cable T-type 5.5x2.1mm connector.<\/li><li>How to use: This is a plug-in power supply and the headers below the board simply plug-in to the breadboard. Once plugged in, the voltage rails to both sides on the breadboard then provide power. You then use the yellow jumpers to select the voltage levels required. This is a dual output 3.3 V, 5 V regulated board and you can have either voltage on either rail on the breadboard, which is very useful.<\/li><\/ul>        <\/div>\n    <\/div>\n\n    <div
