ALAMSCN 3.3V 5V MB102 Solderless Breadboard Power Supply Module with 9V Battery Clip Power Cable 2.1x 5.5mm Male DC Jack Plug for Arduino Pack of 3

ALAMSCN #ad - 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. You then use the yellow jumpers to select the voltage levels required.

With 9v battery snap power cable T-type 5. 5x2. 1mm connector. Hence, if you wish to use it to its maximum capability you will need to remain in that range. There is a green led to indicate the presence of power, and an ON / OFF latching switch to control the power to the board. The input voltage through the barrel socket must be between 6. 5 v and 12 V. Once plugged in, 5 v regulated board and you can have either voltage on either rail on the breadboard, the voltage rails to both sides on the breadboard then provide power.

Maximum output current to be 700 ma. How to use: this is a plug-in power supply and the headers below the board simply plug-in to the breadboard. This is a dual output 3. 3 v, which is very useful. This is a non-adjustable fixed power supply model, which is good enough for most applications.
