How-to: Internal bluetooth to Asus Eee PC 900


I'll be posting series of mods for Eee PC 900 in next days.. first up bluetooth..

Click here to see more


As Asus has connector pins for bluetooth already on the mainboard this is easy mod for anyone who can solder.

As you can see from the picture, there is nicely room for the module. I'm using 3 volt bt module but if you want to use 5V normal usb dongle, you should either check if it has 3V input too or use 5V pin near the webcam connector.

If you don't want to solder straight to mainboard, you could use webcam wires and install USB hub near the bluetooth module.

Next up 3G, fingerprint reader, touch and ..

Hey JK,
Nice mod and it looks, to my untrained eye, to be easy. Do you think it's easy enough for someone who hasn't soldered?
What gage wire did you use? And any chance of a high res picture?

Cheers.
Mark.

if you have never soldered before, do not attempt this. soldering always seems easier than it is in pictures because they are enlarged. also, you'd need to know how to get the connection to stick properly, which can take practice.

use the usb hub method instead.

I disagree entirely.

I will say that soldering will take some degree of practice AND that you definitely need to spend some time (maybe half an hour) with a cheap circuit board from radio-shack, a soldering iron, solder, and some standard wire.

Still, having never soldered before, I recently rewired my guitar and soldered in a kill-switch two weekends ago and it was fine.

Here's a link to help you out, if it's not too late:

I think it's better for us to empower one another than to mystify modding for our own egos.

Cheers!

hey i have a question about the yellow wire coming from your bt dongle to the 6th pin on the motherboard. where on the bluetooth dongle is that coming from?

AndyMac said...

Hey JK,

Nice Mod,
Which bluetooth module did you use for this and where did you get it from?

Thanks
Andrew

JKK said...

my bt is QBTM300..

I took it from another umpc.. a broken one..

yellow wire is for turning the bt on and of, but it doesn't work with that module..

Noel said...

oh okay
i remember searching around the eeeuser forum about that pin being used for bios recognition and hotkey functionality possibly..
id like to get that feature working though just to turn bluetooth off and on

Anonymous said...

Are your upcoming mods going to have videos of them?
Please do Its better when you can watch it!

Noel said...

i got my bluetooth working with bios recognition =]
thanks for the tip on the 5v location
hope you post another inspirational mod

AndyMac said...

noel: which bluetooth module did you use? do you have some pics with the module?

Noel said...

i do have pics,
i just used a regular bluetooth dongle by kensington
i took off casing, ripped off usb connector.. and soldered wires to their corresponding places on the motherboard
ill post a topic on the hardware and mods section in eeeuser.

Pin 8 is +3.3V

Hey JKK where did you get your bluetooth from? and what model?

Thijs said...

It took me 30 minutes to get it done, most of the time was spent opening the case...

The trick is to use the right connections when connecting a BT USB dongle. When you look at the connections with the connector facing towards you, the pins from left to right:
- ground
- USB TX1
- USB TX2
- 5V

The UPPER connection of the two visible in the picture is TX1.

BadZad said...

can i also use that location for soldering a hub on it or are there any differences to normal usb-connectors?

BadZad - an easy way to get 5volt is off of one of the external usb ports
