==Pinouts==
 
−
Here's a list of pinouts for the various connectors and boards.
 
−
 
 
−
Here's a pic of the board, some of the pinouts can be seen on it. [http://pandorapress.net/files/2010/02/rev5.jpg]

''What does it have?''
 
−
* UART2
 
−
* UART3
 
−
* TV out
 
−
* Stereo line out
 
−
* Stereo line in
 
−
* The UART lines can also be used as GPIO (six of them) and PWM lines (four of them).

''Where can we get the connectors from?''
 
−
 
 
−
* The connector appears to be a Tyco Electronics connector, part number 1717169-2
 
−
* The manufacturer does *not* stock these for engineering samples, and very few vendors carry them
 
−
* Community member [http://boards.openpandora.org/index.php?/user/157-wizardstan/ WizardStan] has ordered a bunch and is selling them at $2 a piece plus shipping from Canada, [http://boards.openpandora.org/index.php?/topic/2675-ext-connectors/ see here (thread)] or [http://pandorapress.net/2011/05/18/ext-connectors-have-arrived/ here (article)]

===How Do I Make a TV-Out Cable?===
 
−
* There are some useful tips in the [http://boards.openpandora.org/index.php?/topic/2675-ext-connectors/ EXT Connectors] thread.
 
−
* <del>A guide explaining one way of creating the video cables can be found [http://www.mediafire.com/?8gev3n938go9im0 here] (mediafire link) (dead)</del>
 
−
* MarkoeZ Has written a blog post about it [http://markoez.pirategames.co.uk/index.php/blog/pandora-ext-tv-out-explained/ here]

==Battery==
 
−
[[Image:Battery.jpg|thumb]]
 
−
* 3.7V
 
−
* Lithium polymer single cell battery
 
−
* 4000 mAH, 4 AH
 
−
* battery cover here: [http://www.openpandora.org/images/Battery2.jpg]

−
===LCD===
 
−
* TD043MTEA1 [http://beyondinfinite.com/lcd/Library/Toppoly/TD043MTEA1.pdf datasheet]
 
−
* LTPS (8-bit parallel input for R, G and B, with separate horizontal and vertical sync)
 
−
* 3.3V?
 
−
 
 
−
===UART===
 
−
* UART2 and 3 are available via the EXT connector, and via internal solder pads on the latest revision
 
−
** UART2 appears to support hardware flow control with RTS/CTS lines
 
−
** In the 2.6.27 Kernel UART3 is /dev/ttyS0
 
−
 
 
−
===GPIO===
 
−
* 6 are available on the EXT connector
 
−
* 7 are internal, 2 of which can be used as extra shoulder buttons
 
−
* 1 located on the LCD cable
 
−
 
 
−
===JTAG===
 
−
* Yes, 1.8V 10-pin (board label JTAG)
 
−
 
 
−
===I<sup>2</sup>C===
 
−
* One at 1.8V from the OMAP (board label I2C3-1V8)
 
−
* One at 2.8V (board label I2C3-2V8)
 
−
 
 
−
=== USB ===
 
−
* No internal USB ports
 
−
 
 
−
===Keypad backlight===
 
−
* ?
 
−
 
 
−
===Extra LEDs===
 
−
LED7 and LED8 can be added. You need to add FETs (Q17 and Q18) and resistors (R165, R166, R167 and R168)

==Breakout Board==
 
−
[[Image:Breakoutboard.jpg|thumb|alt=Developer's breakout board|Developer's breakout board]]
 
−
This is the breakout board used by Pandora team members during development. Only a small number were made, and they are not available to the public. However a similar product (or gerber files) may be released in the future. A schematic for this board is available here: http://openpandora.ca/schematic/AV_Board_schematic.pdf
