Power 3.3V / 5V Supply Module for MB102 Bread Board

Pros: What I got was rather different to what's in the photo here. Perhaps you will too. I've uploaded pics, but they're taking ages to show up. But I think it might be an upgrade. Essentially, it's the same thing, a breadboard-able power supply. The input is via a barrel connector, as here, and also via a USB socket. The placement of the output pins is the same, meaning it is a good match with http://dx.com/p/solderless-breadboard-with-400-tie-point-white-121534 as it plugs right into the power rails on those sized boards. Those pins are in two groups each, which might make it more stable than the one shown above. It also has pins on top of the board, could be very handy. It has an on-off toggle switch, and an LED. But the major pro is that the board can do both 5v and 3.3v at the same time, supplied to each of the two rails. You can select the voltage for each rail independently, using jumpers. The USB socket is a female type A, ideal for powering any USB gadget.

Cons: The USB socket is a female A, the same as you would find on your computer. So to power it *from* the computer, you will need a cable with a male A on both ends, or an adaptor. Don't use both at the same time! The board is a bit bigger- it lacks the cutaway section, so it covers up more of your breadboard.

Other: This is a great for when you need to prototype something quickly, especially if you need dual-voltages. Some microcontrollers need 5v, but a lot of external ICs will want 3.3v. Or you might have a lower power microcontroller, but wanting to power a white LED requiring more power.

Pros: 5v to 3.3v to power almost any project. Good design, one must consider jumper settings according to your needs. It is very practical to have all voltages directly from the module. Works with virtually any DC power supply. The POWER provided by the module is very consistent.

Cons: In some microcontroller projects was necessary to place a power supply with a good filtration. Surely not a module problem but it is important to consider. This will prevent random problems in the operation of the microcontroller.

Other: Simple, inexpensive and functional. 3.3v is great for many devices.

Pros: Can use both 3.3 and 5 volts at the same time. Just had to figure out how the jumpers work. (Not to hard, but no instructions) Takes both USB and barrel connectors although never connect at the same time!

Cons: A little tricky to figure out how the jumpers work, but this is a minor issue. I would still recommend it, for the price.

Other: Get one if you need it.

Pros: It get's the job done. The top and the bottom pins can be changed separately to +5V or +3.3V, so you can use it to power 3.3V Display and 5V ICs at the same time. It fits perfectly on the breadboard. It has a on/off switch so you won't need to unplug the cable every time you want to turn the power off.

Cons: Mine was different than the one in the picture. It has a rectangular shape and after you put it in the breadboard it takes away some of the prototyping space.

Other: Quite nice product. Would recommend it to anyone that is using a breadboard to prototype.

Pros: It's small. You can power it you can feed it via USB or via barrel plug, it has a jumper for voltage selector between 3.3 and 5v. I test it with a multimerter and works really nice.

Cons: Mine is not like the one on the photo, It is rectangular and occupies prototyping space on the breadboard.

Other: I think these feeders breadboard are most useful when feeding our prototypes. As always we can buy some more expensive and maybe better but for this price, what can go wrong?

Pros: Just love it - very simple and convenient solution. You can power on it from usb or from power adapter (or even from battery if you want and have adapter cable for that - from 9v battery to 2.0 connector). You can easely get power from socket on the board or you use it on breadboard and you can choose separately whist voltage you nee on right and left sides of board - any combination are esely selectable by jumpers and you understand them without any manual

Cons: It is not like as on picture. It is a shame dx.com do not correct the picture after so many reviews about that. I reality it has more 'height' so it occupy more space on the breadboard. But not significant.

Other: Would recomment for breadboards prototyping

Pros: It's a really piece, well made, beautiful and really useful. It has indepent voltage selectors for both sides , so you can have 3.3V on the left and 5V on the right side. There is an internal voltage converter.

Cons: The board is different from the image, it covers some rows of the bread board. Instead of jumpers, it could use some switches for selecting voltage. For me, another type of USB plug would be better, since it's much easier to find them.

Other: If are curious to try, buy it

Pros: It is very easy to use. You can select 5V or 3.3V on one rail with the switch, and the other rail is always 5V. Very useful in projects that need both voltage levels. A red LED indicates it is on. Mine is exactly like the one in the photo, and occupies very little space (only takes one row of the breadboard). Fits the breadboard well.

Cons: It does not have a power on/off switch. You will have to unplug the USB cable or the DC plug.

Other: I recommend this item. Its very small, easy to use, ideal for small electronics projects.
