Finding Serial Interfaces (UART)

Discovering UART with the JTAGulator and connecting to it with UART PassThrough and a USB-to-UART!

Introduction

UART stands for Universal Asynchronous Receiver/Transmitter, however in the context of Hardware Hacking we’re generally looking for an serial interface which will give us text output from the system and possibly allow for command input. The general intention from the manufacturers point of view – is to allow easy debugging, both out of the factor (to check the system is working as intended) and if a device is returned as broken.
