Tektrum Externally Powered Solderless 1660 Tie-Points Experiment Plug-in Breadboard with Aluminum Back Plate, Jumper Wires, Power Module, Wall Adaptor for Proto-Typing Circuit/Arduino/Raspberry Pi

hi guys it's Sebastian here again today I wanted to show you guys a breadboard power supply that I bought off I think it was banggood and that's really good useful piece of equipment especially for put a typing and I just want to show you guys and take you through the features and just give you an idea of what what it's all about so this breadboard power supply that's selectable 3 volts or 5 volts it has both regulators on board so you can actually switch it out with a jumper depending on how many voltage voltages you need it's got a DC jack the 2.1 millimeter DC jack that's pretty much standard it's got the switch on and off a latching switch it's got the LED power indicator and it's got an additional break out there if you need to power 3 volts or 5 volts somewhere else so let me show you how this works so I've got my breadboard here with the little Arduino Pro Mini installed and this
