Being inexpensive, it does have some limitations but it works well as long as you stay within those limitations which are outline below.

If you have a nice bench supply, this can be used to free-up your bench supply for other duties. The plus sign should line up with the red stripe and the minus sign with the blue stripe. The module has 2 sets of power pins on the bottom. If you install the module so that all of the pins are inserted, the module will be more secure but will block some of the breadboarding area.

You can use the module with only 2 set of pins installed to avoid this, but the module will not be as stable. Jumpers on the board allow you to select either 5V or 3. Moving them to the left applies 5V and moving them to the right applies 3. There is also a small header that provides another place to tap off 3. Power can be input via a standard DC Power Jack. You will see specs on the internet that say you can go down to 6. The reason for that is there is a reverse protection diode on the input which is adding an additional voltage drop before the regulator.

The regulators can technically handle up to 15V on their inputs, but the output current will be more limited with higher input voltages as detailed in the table below and so 12V should be considered the upper limit. In general, running these off a V input will give you the best performance. We have a 7. When this is used, the 5V from the USB is applied directly to the breadboard and also fed to the 3.

When hooking up a device to power it off of the USB connector, make sure that device is not already powered by a different source or damage may result. The button does not have much tactile feel. The power button also controls power to or from the USB port. The output voltages are created using 2 AMS regulators.

The output of the 5V regulator feeds the input of the 3. If you are using both voltages on your breadboard you need to add the current draw off the 3. As with any linear regulator, the power dissipation of the regulator is dependent on the difference between the input voltage and the output voltage.

The larger the difference between the input and output voltage, the higher the power dissipation. For that reason, it is suggested to keep the DC input power in the range of VDC if you want to the maximum current available from the module.

The good news is that if you guess wrong on the current draw, the regulators have thermal protection built-in so if you draw too much power, they will safely shutdown before damage can occur. If that happens, you need to look for ways to reduce your power draw or perhaps use a lower voltage power source to power the module from to reduce the power dissipation.

Toaster contains three power rails to give voltages from 3.

Toaster came about when I wanted a simple breadboard power supply that could power my standard 3. Since most breadboards these days seem to have dual supply rails, I decided to make something to fit the need and so Toaster was born! Toaster is simple to use, simply plug it into your breadboard and then into a USB port or charger.

Toaster will then provide you with 3. All from a single 5V source! Toaster uses a really neat piece of electronics called a DC to DC converter which allows a smaller voltage to be boosted up to a larger voltage.

Fantastic for powering all sorts of analog circuits! This voltage step up does come at a cost however, the higher the voltage that you want, the more current the Toaster needs to draw from the USB port to achieve that voltage. Check out the table below to see the maximum current for each voltage setting. There is an inbuilt 1. The higher the quality cable you use, the better since good quality cables can handle a higher current draw from your USB port.

For those working with Fritzing, I have a 'virtual Toaster' available for download which you can import to play around with. You can download that here: Toaster Fritzing Design File.

Steve April 25, Junee, NSW, Australia. We recognize our top users by making them a Tindarian. There isn't a selection process or form to fill out. Log In. Designed by bradsprojects in Australia. More Info.I needed a new one anyway because my old one died because of a cat with sharp teeth.

I think that it is safe to say that most of the people who make big or small electronics-projects have a pc or laptop in theire hobbycorner and a lot of projects need 5V for IC's or microcontrollers.

So using power from a USB cable isn't that farfetched and lets face it: a lot of devices around us use a USB-connection to get their power or to charge their batteries.

Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. The pins always have the same function for all types of connectors. I made it but slightly differently. Since breadboard power lines breaks in the middle I've decided to made it with double headerpins and the usb in the middle so to put it in the middle to power both lines at the same moment.

Also I've added a couple of female headers to allow eventually to jump directly from the power source to the breadboard but also to be able to give power source from other than USB, like an external power supply. It is very useful, thanks for the idea. Reply 3 years ago.

Nice this was very easy to make instead of the other complex ones. I feel like this would work for people who are kinda of in a rush and is looking for good quality. Now if i was to add a 8 pin push switch it would be between the resistor and the Led right? Reply 8 years ago on Introduction. Unfortunately with this design you don't have access to mA.

You only have mA maximum. The USB specification will supply mA to anything on the bus, but it's designed to only supply its maximum mA once the hardware in the device has introduced itself and sent a higher power request. There are rumours of Apple building high-power USB ports into their newest computers that will supply between 1 and 2 amps. That's so you can speed-charge an iPhone4 or an iPad without using a mains charger. Reply 9 years ago on Introduction.

Just an idea, could you not run your breadboard from 4 X 1. This would give you the instant current when demanded and still be trickle charging at the same time. Saying that, i have a 4 X AA cell nicad charger, and looking inside that, all 4 cells are connected directly to the 5v USB bus!

I forgot toput it tat way in the instructable indeed. I made this quickly to do some testing while using the 5V from my laptop. I did not need more than mA and it still works fine for most of the smaller projects I do.Pages: [1] 2. Read times previous topic - next topic. SamuelAtk Guest. I don't know it for all models, but the Uno can be connected to external and USB at the same time. It's possible Quote from: bakkerl on Oct 22,am.

Quote from: JimboZA on Oct 22,pm. It does the sensible thing. I would have thought that the USB interface would always only be powered from USB power and that if there is no USB power, it has no function, but that may not be the case. If power greater than 6. The circuit is admittedly, a trifle indistinct. As long as it is in fact, 5V, this should cause no actual harm; the polyfuse will limit current flow. Ghostbird Guest. Sorry for the necromancy, but I thougth this was a better option than starting yet another thread on this.

I need sufficient power for the LEGO motors. It's not that much power actually, but more than the Arduino can supply.

I power the arduino trough an exteral adapter rated 12V 1. The crane runs a demo program at the moment, and will operate with a limited AI once I can get the LEGO light sensor installed in a way that works with the rotating claw. I want to be able to read data from, and write instructions to the Arduino using the USB interface virtual serial interface. However when I connected both external power supply and USB, I started to smell the characteristic smell of a frying PCB, and I quickly disconnected the power, before anything was permanently damaged.

I doubt my laptop is connected to ground, since the anodised aluminium parts feel slightly electrified, and there are capacitive touch buttons above the keyboard. The arduino is definitely not connected to ground, since the adapter has a non-grounded plug.

I am a software engineer that recently started dabbling in electrical engineering, so I am limited in my understanding of these things, and I thought it would be safer to ask, than to risk fry the board.

On my Uno, I can connect both the external power source and USB, and the board will select the input with the higher voltage as the power source. I assume, an official Leonardo would do the same thing, but you will need to delve into the datasheets of your work-alike to make sure it does that. Also, be sure you plugged your 12v power supply into the correct side of the voltage regulator. These microprocessors don't like 12v running through them.

Finally, 12v is getting up to the high end of recommended voltage on the Arduino. You might want to use a multimeter to verify that your power source is 12 volts. Basically you connect the grounds of the motor's power source to the ground of the Arduino, and then wire the the power source to the power pin of the motor, but connect the control pin of the Arduino work alike to the microprocessor.

Quote from: Ghostbird on Nov 10,pm. I will not explain the full details of my project set-up here. Since I did so twice, and both times my work was gone. After the first time I did not understand why, but after the second time I realised that the Arduino Forum login time-out is too short to write it down.
