Touch Screen Cable Tracer

Diagnose the type and integrity of USB and RJ45 cables with this Touchscreen Cable Tracer. Identify the exact wiring configuration, diagnose broken wiring, and plug pin connections.

- Test over 10 cables types using RJ45, USB B/B3, USB A/A3, USB C, USB Mini, USB Micro/Micro3
- Touch screen menu Auto Detect Mode and Manual Mode for a deeper diagnosis
- Displays Loop-back of pins on any of the input and output ports in use

Based on the popular Arduino Cable Tracer the Touch Screen Cable Tracer is 70% smaller, uses an Arduino shield that eliminates over 20 hours of meticulous soldering, and uses snap-together parts with minimal soldering.

I have tried to minimise the number of parts to make this more accessible to makers of all skill levels
