==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]
 
 
 
==Ext Connector==
 
[[Image:Cable_connector pinout.png|thumb|TV cable connector]]
 
''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
 
 
 
==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]
 
* reading out battery information: [[data provided by Battery and Power driver]]
 
 
 
==Internal connections==
 
 
 
===LCD===
 
* TD043MTEA2 [http://beyondinfinite.com/lcd/Library/Toppoly/TD043MTEA2.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
 
 
 
===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===
 
* ?
 
 
 
==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
