Dual Unregulated Power Supply
 
Four on-board 100V, 3A diodes plus 2200uF/50V electrolytics to provide an unregulated power supply from a center-tapped transformer. Many power amplifiers require a dual DC power supply for their operation. Usually this consists of some diodes and electrolytic capacitors to convert an AC voltage to a +/- DC voltage. This simple kit does just that, with all the components mounted on a small PCB to avoid the usual spaghetti-wired mass (mess?). The kit is constructed on single-sided printed circuit board. (CPS114)

Power supply voltage adj. 1.5 to 30V kit  (Out of Stock)
 
This is a basic adjustable voltage power supply using the popular three pin regulator, LM317T. You can select any voltage between 1.5V and 30V using a potentiometer. The LM317T is rated at 1.5A so you must use a larger heat sink when drawing high currents. Unregulated AC or DC input via terminal block or power jack. Requires a suitable transformer.(CPS68)

Dual Unregulated Power Supply (kit)
 
designed for our CPS106 audio power
amplifier. It is also suitable for any power
amplifier module or circuit requiring a
positive and negative rail voltage of up to
45 Volts per side. The output voltage and
current will depend on the transformer
chosen, and this is not supplied with the
kit. Never use a transformer larger than
35V-0-35V, as the capacitors voltage
rating will be exceeded. (CPS186)

    Breadboard Power Supply 5V/3.3V
     
    Description: A very simple breadboard power supply kit that takes power from a DC wall wart and outputs a selectable 5V or 3.3V regulated voltage. The .1" headers are mounted on the bottom of the PCB for simple insertion into a breadboard. Pins labeled VCC and GND plug directly into the power lines. The lone pair of pins have no electrical connection but help support the PCB.
    There are two pins available within the barrel jack footprint. Any stripped +/- DC supply can be connected instead of the barrel connector. Board has both an On/Off switch and a voltage select switch (3.3V/5V).

    Comes as a bag of parts kit and is easily assembled if you can follow the silkscreen indicators and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes.

    Check out Sparkfun's Unregulated Power Supply Tutorial!

    Includes:

    • DC Barrel Connector (2.1mm center positive)
    • TO-220 Voltage Regulator (LM317 1.5A max current)
    • 1N4004 Reverse Protection Diode
    • 100uF 25V Capacitor
    • 10uF 25V Capacitor
    • 0.1uF 50V Capacitor
    • Red Power LED - High Brightness
    • 2pcs SPDT Slide Switch
    • 4pcs 0.1" Header Pins
    • 2pcs 330 Resistor 1/6W
    • 390 Resistor 1/6W
    • 240 Resistor 1/6W
    • Bare PCB with Silkscreen Indicators
    • PTC resettable fuse

    LilyPad Power Supply
     
    Description: A small, but mighty power supply. This board was designed to be as small and inconspicuous as possible. Pop in a AAA battery, flip the power switch, and you will have a 5V supply to power your LilyPad network. Good up to 100mA. Short circuit protected.
    This board has AAA battery clips but can use an input from 1.2V to 5V. Our lithium polymer batteries are a good, rechargable alternative.

    LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable - but be sure to remove the battery!

    • 56x26mm
    • Thin 0.8mm PCB

    LilyPad LiPower
     
    Description: A small, but very mighty power supply. This board was designed to be as small and inconspicuous as possible. The nice thing about LiPower is the ability to use rechargable Lithium Polymer batteries. These batteries are smaller, flatter, and last much longer than a AAA battery. Attach a single cell LiPo battery, flip the power switch, and you will have a 5V supply to power your LilyPad network. Good up to 150mA. Short circuit protected.

    This board has a JST connector, which will connect to our JST terminated single cell 3.7V LiPo batteries. It also has terminals for charging the LiPo battery with one of our LiPo chargers.

    Power Driver Shield Kit
     
    This shield allows you to use a computer power supply (or other power source) to use your Arduino to switch high current. With RFP30N06LE MOSFETS, you can easily control a lot of current directly from your Arduino. 

    The board provides 6 PWM outputs via screw terminals. Check the datasheet for the MOSFET below for full specifications on how much current this board can handle.This board is a very easy way to start using MOSFETS for your next high current project.

    A protection diode has been added to the power input of this version of the board.

    Note: If you want to stack another shield on top of this one, you will want to double-up on the stackable headers to clear the MOSFETs.
