Making an RS232 level converter for the Pandora

How is this done?

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. [1] Board with many components labeled. [2]

Ext 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).

What is the pinout?

• The pinout of the Ext Connector

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

• 3.7V
• Lithium polymer single cell battery
• 4000 mAH, 4 AH
• battery cover here: [3]
• reading out battery information: data provided by Battery and Power driver

Internal connections

LCD

• LTPS (8-bit parallel input for R, G and B, with separate horizontal and vertical sync)
• 3.3V?
• TD043MTEA2 datasheet

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
• Are there any internal?
  • 7 are internal, 2 of which can be used as extra shoulder buttons
  • 1 located on the LCD cable

I²C

• 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

Maximum current draw?

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
