## Questions & Answers

**Q: Is usb both input or output?  victor says can provide input power through the usb plug.  tam says the usb can power other devices?  so, i or o?**
A: Answer for YuRobot MB-V2, which seems to be the same device: The USB connector powers my Arduino board correctly. Therefore it delivers the requisite 5V 500mA OUTPUT. Trying to power this from a 5V INPUT would be complex, as the circuit loses voltage as it converts its minimum 6.5V input to 5 and/or 3.3V output. Perhaps this is why one reviewer complained he got no more than 3.8V at the 5V output pins--he may have been trying to use a 5V power supply connected to the power input connector.

**Q: what size is the power connector?  why won't companies publish this information?**
A: 2.1 mm center high.

**Q: What is the max current this could draw from batteries? also, if i don't pull 700 ma on the breadboard, will it still pull 700mah from the batteries?**
A: I doubt that this alone pulls a lot of current.  there is a few chips on the board and one LED, so I would guess under 100ma.

**Q: I had an input of 12v, jumper in 5v position, but my volt-meter was reading 9v? 3.3v jumper worked for the 3.3 volts, but what’s with the 9v?**
A: Checked the output power to see if it's puting out 9v or 5v.

    Works well with USB power
  

*by D***N on Reviewed in the United States on 14 October 2016*

I was a bit hesitant at first to try these out on an existing project, so I put it on a blank board with my multimeter. Sure enough, it puts out a steady +5V and +3.3V depending on the jumper configuration at the top. For the record, I used USB power off a laptop.As someone else stated, these are compatible only with the newer solderless breadboards out there, such as the

    . If you have an older style breadboard with wider distribution gaps between power rails and the board, this will not fit.It does tend to eat up space on the end when mounted properly, so you will lose the ability to use some of the board tie-in points. Thankfully it's not so big as to cover more than 5 or so rows. Also, be extra careful that you mount it on the rails with the correct polarities. If you're following the power rail guidelines for positive and negative, that means there's only one particular end of the breadboard they can go on to match (assuming you're using an MB-102 board).

I have purchased two of these units.  Both units only deliver 2.6v when the jumpers are set to 5vthe 3.3v is coming in at 3.5vI returned the first unit thinking I got a bad one.  I purchased another unit and I get the same think.I'm out on this one. Failed x2

*by P***R on Reviewed in the United States on 15 November 2016*

no voltage protection, if you accidentally short this it will dereglate and give you 12 v rails forever on the 5v line . I think the converter chip they use is the culprit.
