Please add to this if you have any information

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]

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?

Where can we get the connectors from?

Battery

3.7V Lithium polymer single cell battery 4000 mAH 4 AH battery cover here: [2]

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?

Battery

JTAG

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
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
