Wizard pin out

mini usb pin out
i want to use BT car charger for my wizard

Pinout for Mini USB Connector is:

1: +5v DC
2: Data -
3: Data +
4: GND

I'm not quite sure what your trying to use to power it but the voltage must be between 4.75 and 5.25V otherwise its gonna get a bit upset!

I want to use BT-338(http://www.globalsat.com.tw/english/products_detail.php?main_id=20&p_id=74) car charger

On AC power supply of this device are writen +5V 1.2A i hope that car charger will be the same voltage?

The car charger will give out the same voltage but I would put a voltmeter across it anyway just to check and also to confirm the polarity as this could well upset the XDA! The highest amperage across a USB bus is (I think!) 500mA but a 1.2A supply will be ok as the device will only pull what it requries. Don't try and power both devices off the same charger though (just checking this isn't what your trying to do) as there won't be enough power to go around.

I was just thinking about doing something like that. How much power does the BT mouse require? Given the XDA can be powered from a standard usb connector it doesn't require more than 500mA. So do you think 700mA aren't enough for BT mouse??

yes i will do this

i will use for xda or for gps...

I have no idea to be honest! I havn't used it but it would be worth checking before trying!

barnesdmd: thanks working fine

It "should" be fine to power both off a 1.2A supply (although i dont know if the car charger will be able to supply this or not. mains - 5vDC is very different electronics to 12vDC-5vDC). The worst that should happen is that the GPS needs a large power supply, and the voltage supply will drop (what happens if you draw too much current) The Wizard should then just ignore the useless voltage (below 5v) and not be worried by it.

This is all should and not will, i dont know what components are fitted in the Wizard charging & power circuit.

I haven't tested it personally but do have a reasonable knowledge of electrics & electronics

Can anybody here who has a GPS bluetooth mouse have a look on it's specification? There we should see how much power it requires, so we could be sure :)
