This adapter allows you to connect a barrel jack connector to bare wires. One end has screw terminals and the other has a 5.5x2.1mm, center-positive female barrel jack. If you have a power supply with a barrel jack and want to plug it into a breadboard,...

Li-ion Charger 1000mA, 8.5V  The LED will be red when charging and turn green when charging is done.

Packaged solar cell.   This unit is rated for 8V open voltage and 100mA short circuit (9V, 1W) Termination is soldering pads. Unit has a clear epoxy resin coating with hard-board backing. Robust sealing for out door applications!

This is a nicely enclosed unit that takes an AC supply between 85V and 265V and steps it down to 9VDC at 2300mA. Contains 5 screw terminal, two for AC input, two for DC output and one for a common ground.

We designed this 5V and 3.3V regulated DC power supply for rapid prototyping. This board accepts a norminal 9V-12V 2.1mm Barrel connector, and outputs regulated 5V and 3.3V with a combined 200mA.  The 5V and 3.3V output headers are standard 2.54mm...

High quality switching 'wall wart' AC to DC 5V 3000mA wall power supply. These are switch mode power supplies which mean the output is regulated to 5V (no more 14V outputs!) and the capable output current is much higher (3000mA!). Please note, this...

High quality switching 'wall wart' AC to DC 12V 1000mA wall power supply. These are switch mode power supplies which mean the output is regulated to 12V and the capable output current is much higher (1000mA!). Please note, this specific supply (12V/1A)...

This handy multi-cell lithium ion battery meter can be used to monitor each cell of a multi-cell lithium ion battery pack over discharge. It will display the voltage of each cell, and the overall pack. The connector is -, 1, 2, 3, 4, 5, 6 (+) of each...

 If you need to charge LiPo batteries, this simple charger will do just that, and do it fast! The USB LiPo Charger is a basic charging circuit that allows you to charge 3.7V LiPo cells at a rate of 500mA or 100mA per hour. It is designed to charge...

Embedded AC to 12V Power Supply Module: output of 12V with current up to 500mA
