=== Where can i get more documentation (manuals,schematics,...)? ===
If you need more than these wiki pages, you can get manuals from www.igep.es [http://www.igep.es] website. You need a free self-registered user account and go to download validated user section.
Another hard way is access to public git repositories [http://git.igep.es] and search pending-documented features inside source code. <br>

=== Is it possible to connect a battery to maintain the real time clock in the board? ===
User can use i2c external rtc or connect externally a super-cap/rechargable battery on R768 pins.
R768 is 0 Ohm resistor connected between GND and BKBAT (M14) input from TPS65950.
IGEPv2-RC has available unpopulated a super-cap/rechargable battery footprint (BT741) for real time clock backup battery
=== How to connect Bluetooth chipset to OMAP&nbsp;? ===
*Control serial link uses OMAP3 UART2.*Audio link use OMAP&nbsp;McBSP3 and TPS65950 audio codec + mixer<br>
=== How many UARTs are available? ===
UART2 --&gt; bluetooth
UART3 --&gt; debug console on connector J960
</pre>
OMAP3730 has 4 UARTS:<br>
<pre>UART1 --&gt; RS485 on connector J940
UART2 --&gt; bluetooth
UART3 --&gt; debug console on connector J960
UART4 --&gt; (NOT&nbsp;AVALIABLE on IGEPv2: it uses GPMC_WAIT2 and GPMC_WAIT3 pins)
</pre>
All of this UART are also available on other connectors:
UART2 --&gt; on expansion connector J990 without bluetooth feature.
UART3 --&gt; on connector JA41 without DVI transceiver with CMOS 1v8 logic.
</pre> Read HOWTO use [[Serial_Debug_ConsoleSerial Debug Console|debug serial port]].
=== Is it available s-video or video composite output? ===
**McBSP3 interface is used by TPS65950 PCM&nbsp; interface and Bluetooth PCM interface of built-in wifi/BT module.
*IGEP0020-RC2 model (no WIFI): these boards are fully functionality compatible to other third boards and all pins are free available (they aren't shared).

=== What is the max Ethernet throughput with LAN9221i? ===
 
The [http://en.wikipedia.org/wiki/Ethernet ethernet] throughput it's 94-96 M/bits second, [http://www.smsc.com/index.php?tid=145&pid=116 LAN9221i] it's connected direcly to OMAP processor addressable space and dedicated IRQ (no USB, SPI, converters ...).

=== Is it possible to config the wireless LAN and bluetooth so they are completely off, and not consuming any power at all? ===
We change GPIO_94/GPIO_95 of IGEP0020-RB1 version to GPIO_138/GPIO_139 IGEP0020-RCx version because GPIO_94/GPIO_95 are camera interface lines.<br>
Linux kernel autodetects B or C assembly configuration. See [[Frequently Asked Questions and Their Answers#Which_revision_is_my_IGEPv2_board.3F|IGEPv2]] boards and [[Frequently Asked Questions and Their Answers#Is_it_possible_to_config_the_wireless_LAN_and_bluetooth_so_they_are_completely_off.2C_and_not_consuming_any_power_at_all.3F|IGEPv2-RCx PCB compatible IGEPv2-RB1]].<br>
=== Could you attach an LCD with LDVS interface? ===
=== Is there a way to attach a VGA monitor directly? ===
You can IGEPv2 doesn't have VGA output. But it could be use &nbsp;:<br>  *DVI to VGA converter connected to DVI output. *IGEPv2 EXPANSION expands IGEPv2 capabilities. Among other things provides the VGA&nbsp;interface on D-SUB15 connector.<br>
=== Is it possible to connect a CMOS sensor (ie are the camera signals available on a board connector)? ===
A popular Hirose U.FL (MHF IPEX) connector to SMA-RP (reverse polarity) connector cable fits in
<&lt;br>&gt;
</pre>
 
=== Is it possible to add analog video output? ===
TP401 = TVOUT_1R sch signal = PIN 3 S-video connector = Y = luminance
TP400 = TVOUT_2R sch signal = PIN 4 S-video connector= C = chroma
</pre> 
=== Is it possible to power using USB OTG connector? ===
No, it is not possible on IGEPv2 boards
=== What is the maximun power consumption? ===
U-Boot command line is a [[Serial Debug Console|serial tty console]]. IGEPv2 normally uses UART3. So, you need send any key to [[Serial Debug Console|serial port]] using some serial terminal application.
'''Look up! ''' Don't press any key of any usb keyboard connected to IGEPv2, you need press any key of your computer keyboard attached to [[Serial Debug Console|serial link]] to IGEPv2 ( serial cable + minicom or other serial terminal application ) <br> <br>  ---- <br>  ---- <br>  ---- <br>  <br>  == IGEPv2 EXPANSION hardware related questions == === Which revision is my IGEPv2 EXPANSION board? ===

=== I would like too to know if the external wifi antena is easy to install? Where can I acquire a compatible external antenna? ===
On Default configuration use internal shared wifi/BT omni-antenna<br>  But, on IGEP-MODULE boardscould be hardware-hacked and disconnect internal antena to populate U.FL connector for pigtail and external antena:<br>
<pre>The J2 is a "HRS (HIROSE) - U.FL-R-SMT(01) - RECEPTACLE, SMT, U.FL " connector
