Kindle debug console connector

To make your own you'll need a 20-pin 0.5mm pitch flat flex cable with a connector. Pin 1 is at the bottom, pin 7 (and 3 and 10) is ground, pin 11 is RX (connect TX from PC here) and 12 is TX (connect RX from PC here). Note that the outputs are TTL levels, you need a TTL-RS232 or TTL-USB converter!
