Small Bluetooth Dongle


UltraPort is nothing else than a standard USB 1.1 interface with a proprietary connector, it's possible to solder any USB device to it. I installed the tiny bluetooth dongle inside the diplay lid, soldered the wires from the dongle to UltraPort connector pinouts.

This is the story, and review:

I bought a small bluetooth dongle, opened it, soldered 4 wires to it and the other end of the wires I soldered to UltraPort pinouts and places the dongle inside the display lid.



The pinouts of the UltraPort Can be found here, I measured the pins and found pin 3 to be +5Vcc and pin4 to be +3Vcc.
I used pin 3 for +5Vcc, pin 6 for D+, pin 7 for D- and pin 13 for GND. I soldered 4 wires to those pins and the other ends to dongle pcb.



One location for the the bluetoth dongle is on top of the lid, unfortunately the antenna will be on the up-down direction, and front-back signal is to weak, so I placed the pcb sicked on the lid, behind the display, antenna on the front-back direction, . I changed the position of the Quartz crystal so the pcb will be thin.

Antenna on the up-down direction, low signal on the front-back direction of the display:


Antenna on the front-back direction, better signal from front of the display(recommended):


Job done.
