W3bMa5t3r's USB Power Modules

**W3bMa5t3r** · 08-01-2007, 08:03 AM

With a growing number of USB devices in my car, and wanting a few of those to be powered at all times, or to be switched on when the car is on, I built two new modules. The main reason was for my GPS tracking phone with Mologogo (boost I455, stays in the car, on all the time), and powering my Samsung A900 when I'm in the car using it for data transfer via bluetooth, cuz it sucks some serious juice doing broadband speeds.

Anyways, hooked them up and things have been gravvvyyy

The modules supply 1.5A of power, USB specs are 500mA per port, so this should do fine.
They have DIP switches to set the powering setup, either Always On, or On With Vehicle.
Just wire up the constant +12vdc, switched +12vdc and ground (and USB cable to CarPC for the first module).

Great for those higher powered devices, charging cell phones, ipods, etc.
Each module supplies up to 1.5A (1500mA).
1500mA for the one port with data pass through, or 1500mA shared for the two port, no data pass through.

More info HERE

The first has one USB port, with data pass-through, the module supplied USB power is isolated from the CarPC.

The second has two USB ports, NO data pass-through.

Great idea. I could use something like this for my USB DVD drive. But my DVD drive draws 1A at 5V. Are you sure your module is 1.5mA? Don't most USB ports put out 500mA?

Sure am. Both modules will supply up to 1.5A total. And yes, the specs for USB ports is 500mA per port. I swear I wrote that above

HEY Steve this should be the thread to ask you this but I have used Boost Mobile on and off. I was just wondering how is the service for you? In my area there is never any service! It just sucks man! It really annoys me cuz i wish it had dam service. And i dont wanna spend another 20bucks (prepaid) to find out if the service got any better!... I would love to use the mologogo and boost but i cant cuz boost isnt good in my area!

Well to pull a quote from the W3bTracker GPS Tracking thread

Oh, and no one had asked about it, but I was running W3bTracker, went into hibernation and back out, it picked up where it left off and kept on tracking. Sweeeet

Hope that clarifies things

But yeah... mologogo/boost was quite shoddy for some reason.

@Sonic... Good sheeet. Yeah I did the same w/ my interior. SEM vinyl dye is my(maybe your) friend. See you there then.

awesome, just what I wanted.

Well really I want a 12 port usb hub powered with those features each port getting 500mA

question, what kindof battery drain have you seen with leaving a device always on. I'm considering leaving my gps puck powered constantly to prevent cold boots.
