Suitable Power Supply for Mini2440

On my Mini2440 + VGA, unfortunately, was no power supply. Can someone tell
me what requirements must be met by a suitable power supply? (Voltage,
current (power), polarity)

5v with 2A rating would be the best

Thanks a lot. I bought a power supply with 5V and about 3A. Unfortunately
the adapter doesn't fit. But I'll try an other power supply next week...

5V/2.5A powersupply damage by Mini2440 + LCD 7" Colour TFT LCD.
Now i use 5V/15A and it works fine!

Ok, about 1A or 1.5A seems to be the best choice. But I can't find any
information about the size of the connector of the power supply. The one I
bought was to big. Does anyone know the right size?

2A is minimum! More is better than less.
I have now fifteen ampere turn! If in any case exaggerated.
2.5 A is evaporated at me.
The connector should have internal dimensions of 1.35 mm.
The allocation is plus the inside and the outside negative.
The best you take the whole board with the purchase.
In the electronics store you get the right plug to solder!
Then you can use the 3A power supply.

Oh ok, I thought you forgot the dot by 15A. Thanks a lot for die info.

I tried to put 5v, 500mA. The indicator of power supply light up weakly.
but no reaction on 4 other LEDs.

Why current also needed to be consider apart from voltage??

The board does not even boot up? If you do not have enough current
capability the supply voltage will either sag below the minimum required to
run the board or hopefully go into current limit and effectively shut-down.

The mini2440 with backlight on draws about somewhere around 1Amp.  A 1Amp
or 1.5Amp supply should be just fine.  Bigger, just costs more.

The connector is a bit difficult, so make sure the power supply works with
your mini2440 and does not shut down if you wiggle the connector slightly.

Think there was another thread on the connector issue.

Good luck

Hi all, I´d like to know the plug conector name of power supply. If
somebody know, post here!

They are a fairly common DC plug connector of the type that come on plug
packs.

Measure the outer diameter with a vernier caliper and check the internal
diameter with a drill bit.  1.0mm from memory, but check it!

The main problem I had, was that the outer diameter seems to vary a bit
from manufacturer to manufacturer.  If is on the loose-side the connection
will be intermittent.

DC-Plug: 1.35mm inner x 3.5mm outer diameter
