HobbyKing Micro UBEC 3A / 5v

HobbyKing Micro UBEC 3A / 5v

This small and lightweight UBEC features a high efficiency switching mode BEC, providing better heat dissipation when compared to linear voltage regulation. The shielded PCB design and output EMF coil provide a stable, low noise voltage output. The HKU3 also features built-in reverse polarity protection.

Output: 5V/3A
Dimension: 22.9mm*20.3mm*7.6mm (L*W*H)
Weight: 7.3g (wires included)

Would this work to charge a go pro while in mid flight?

Yes, Gopro takes 5V so this will be good for it.

I ordered two of these from the US warehouse. What I received look different from what's listed in the product description. What I received, looks more like this: http://hobbyking.com/hobbyking/store/uh_viewit
em.asp?idproduct=52861 Except
it's a 5v/3.5A UBEC. This wouldn't normally be a problem except I'm having an issue with both of them and I can't find specs on these since they are different. I have the UBEC powering a AOIP v2 flight controller. It's connected to a 2S 800mah battery. It's a mini quad with 4 Turnigy 1811 motors. The output voltage is fine (5.15v) until I get past 50% throttle. Then the voltage starts dropping and by 2/3's throttle the voltage is close to 4V and flight controller restarts. The flight controller is only pulling 140mA. I don't have the issue if I use the ESCs to power the flight controller or if I use a larger Turnigy SBEC. Any ideas?

Hello Chris, I discovered that this is really s..t :-( it is build of 2 parallel switching devices. Not even good and reliable enough to power up a led lighting. Lot of noise, unstable as soon as you get some current from it. Get something serious. Enjoy flying

(Hmm...the reply button doesn't seem to be working for me here.)

tehPajka, thanks! Yes, I meant microUSB. Sorry, typed too fast there :)

I was hoping to power it through AAs because I have those lying around but no LiPo's. I guess you meant that [microUSB - anything] cable needs to be obtained elsewhere too?

I still don't understand why I'd need servo connectors in this setup.

I can also get cheap (but less cheap than here) 6AA holders locally (ordering on eBay for one item isn't worth the shipping fee) but was hoping they sell them here (in case i missed it) and I could then bundle the order with the UBEC.

Hello, the reply button will work once you are a Gold member =) good luck going up mate. Cheers

The 6AA holders for 2USD and USB cables on eBay have mostly free shipping. The servo connector is for crimping on the other side of the microUSB cable so you can easily connect it to ESC output. Or you can just cut the one on the ESC and solder the cables together. Its just my personal preference, do it any way you like. B-).

Small, lightweight UBEC. I use it for losi 1 / 24 micro rock crawler, because lipo 7,4 v much for him, and original HiNH 4.8v expensive. This inexpensive but very good solution:)
