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).

Note that Power Out defaults to 2.8V, while the digital I/O lines work with 1.8V logic. To avoid damaging the Pandora, a level shifter will be required for most applications using these signals.


Just for reference: the Pandora-side of the connector is Tyco 1717312-1, you already have that. [1]

Astron Connector

  • Astron, part number 3111014-301-R
  • Available from DragonBox for 7 EUR each [2]

Tyco Connector

  • Tyco Electronics, part number 1717169-2 [3]
  • The manufacturer does *not* stock these for engineering samples, and very few vendors carry them
  • Community member WizardStan ordered a bunch and sold them for $2 each plus shipping from Canada [4]
  • Community members peca and Nardella designed and manufactured a break-out-board for easier soldering [5]
