I have comprised and tidied and enhanced my existing mod. I at present have encompassed internal bluetooth and an internal customary USB socket for internal memory extension. I have comprised and tested the USB socket through a USB flash drive and it works completely. The bluetooth is associated to the miniPCIe extension connector and is modded to run off 3V. The socket is associated to the miniPCIe WLAN connector and has a 5V make available. The USB Connections beneath the mini PCIe WLAN card.

What the connection are you utilizing for the 5v usb port. If I desire to cut the hub commencing from my mod, might I utilize the 5v point and split it for 2 USB devices, one is utilizing the usb+/- commencing from spare slot and the additional from wireless. Would be pleasant to have 2 USB apparatus without the hub and tranquil have them mutually on 5v. Did you reuse wire commencing from a USB cable or did you utilize incredible specific. In the third photo you be able to observe 2 wires going to the similar ground point one is utilized for each USB port.

I had utilized a surface mount USB connector and kynar padding wire wrapping wire. The wire requirements to be attractive thin. Is there several chances with the intention of splitting the solitary +5v connecting a ms bluetooth module and corsair flash voyager might cause several damage. That's the stuff I utilized. It’s improbable to do several harm utilizing the 5V position to power two apparatus as long as they do not take too much power. The devices you are talking regarding be supposed to not take to facilitate much power.

Is your standard wifi card tranquil working or do you encompass to utilize at present a usb wifi. If the standard WIFI card is running extremely well. It did not utilize the USB correlations on the mini PCIe slot. Just wondering if it is probable just to eliminate bottom cover by unscrewing 6 screws to reach the substructure side of the pcb exclusive of touching the rest or you tranquil have to eliminate the keyboard and top cover in addition. Regrettably you have to acquire the complete thing apart to obtain to the bottom of the PCB.

Unless most of them are utilizing a shunt supervisor on the USB stick (unlikely) positioning 3V into a regulator through a 3V output determine to not work. The regulator will encompass an internal dropout voltage (generally >0.7V) so the output might be lower than the flash drive requires. Receiving a PCB completed I'm a freelance electronic engineer and might design such a PCB and encompass it manufactured if sufficient users desire it. I was considering designing such a apparatus previous to I found out the connector was missing on numerous eeePCs.

The merely predicament is that if you utilize the 3V make available on pin 52 of the miniPCIe connector the eeePC fails to boot which is why I utilized a dissimilar 3V position. I have comprised not tried the additional 3V supply pins on the miniPCIe connector. Does not it fail to boot merely if the apparatus is not a mass storage apparatus with an os installed. I believe I read when the open line on with the intention of voltage pin disappears the bios put out of action the internal ssd and give the impression of being for a mass storage apparatus on the pcie socket.
