Hardware hacking

Making an RS232 level converter for the Pandora

How is this done?

Pinouts

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?

Battery

Internal connections

Please add any information you have here

UART

• UART2 and 3 are available via the EXT connector.
  • UART2 appears to support hardware flow control with RTS/CTS lines on the EXT connector.
• Are there any internal UARTs?

GPIO

• 6 are available on the EXT connector
• Are there any internal?

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
