You may add the capacitor in INPUT and OUTPUT line but here I am just Ignore this for now. PIN OUT FOR THIS LM1117 chip: PIN 1 is GND PIN 2 is V out (3.3V) pin 3 is V input (5V / power from USB port). The other chips will also work too - for example lm317 and etc (but here I'll be only talk about lm1117 chip) bellow I am attaching the image and detail each pin of this (lm 1117-3.3) chip. The easiest way to achieve this 3.3v is by using 3.3 voltage regulator from Linier Technology (lm1117-3.3). Which is USB port have 5V whilst the card is require only 3.3V. And here the case, We are using USB port to RUN MINI PCIe device. For most MINI PCIe card, it's require 3.3V to able to run (NOT 5V) - refer to the manufacture datasheet. Step 1: Preparing the Power to the Mini PCIe Card. a cup of coffee and off course a Soldering Iron and the friend.Sim card Slot - To make easy for us to change / replace the SIMCARD (otherwise you can just solder the wire directly to the SIM pin).USB Cable / Cord, Here I am sacrifice my printer cable:).BUT Please note if you are using the old part you have to make sure that it is still work as it's suppose to be. 3.3 Voltage Regulator, here I am using lm1117 which is take apart from my external disk adapter board.BUT if we refer to the mini PCI-e connector I think MOST card will also work. Mini PCI-e Card - (option GMT380 with GPS function) I am not try another type / brand CARD yet, since this card is only the one I have on hand right now, Later if I have a change and get another card, for sure I'll test it.HERE I'll be sharing my experiment (last night) to convert the MINI PCIe card to be able to run with USB port SO LET'S START What you will need: Use this document to help you find and install the correct modem driver update for your HP Pavilion Desktop PC. As the title reads, it is an Anatel WN7600R. I pulled it out but I can't find any drivers for it. Hi all, pulled this card out of an HP desktop that is completely screwed.a bunch of liquid cement got dumped into it.
