Revision 5 units?

Hardware Versions mentions only four revisions:

• First Edition Mark 1 - This is the first release and so has poor build quality for many units.
• First Edition Mark 1 (B) - A second version in which an incorrect resistor was changed to prevent screen flicker.
• Second Edition Mark 1 - The second revision of the hardware covered the battery and power LEDs.
• Second Edition Mark 2

So what is this fifth revision mentioned in the EXT Port article?

Is there a unit called something along the lines of "Second Edition Mark 2(B)". Is this the unit with 5v output? My unit is a Second Edition Mark 2 / GPX-GP2X-F100(B). But according to my multimeter... outputs only 3.3v. Does this mysterious 5v have a different sticker underneath? Sausage 22:09, 16 August 2007 (EST)

I'm inclined to say it's not true, but I'll ask around and find out for certain. Orkie 05:16, 16 August 2007 (PDT)

USB Host on Ext

is possible to extract USB HOST from the EXT port?

Note that there's a USB host on the side. I'm hoping we can use the USB Device of the CPU somehow. -Rek

I do believe that the side is only client only, a method to hook a link cable (using USB) from one GP2x to another for multiplayer games would be awesome though. -Sephiroth111

Serial Tx/Rx

The pinout list say of the EXT port

22. RXD0 / GPD0

23. TXD0 / GPD1

but following the GPIO_Reference, it is

22. GPD0 = UART0 transmit (GP2X->PC)

23. GPD1 = UART0 receive (PC->GP2X)

i am not used to data line definitions and can't confirm. but i think the " -> " is more self-explanatory.Double7 20:58, 29 August 2010 (UTC)

USB Wifi

The USB port does not support a host connection. Which means peripherals such as USB WiFi or Bluetooth dongles will not work. Your best hope is to wait for drivers for an SDIO WiFi or bluetooth adapter.

Thought this would be a good place to add a link to the recent USB_Host work by Art103
