JTAGulator – On-Chip Debug Discovery Tool

Description

JTAGulator

The JTAGulator is a purpose-built discovery tool that identifies JTAG and UART pinouts on unknown boards automatically, saving hours of manual probing during hardware reverse-engineering.

It brute-forces channel assignments across up to 24 I/O lines and reports the working combinations, turning a tedious guessing game into a quick, reliable step. It’s a staple of any serious hardware-hacking bench.

Key features

• Automatically locates JTAG (IEEE 1149.1) pinouts
• Identifies UART pins and detects baud rates
• Up to 24 channels at adjustable target voltages
• USB serial control from any terminal
