The Arduino cable tester is equipped with a touchscreen the Cable Tracer builds on a previous project that is now 70% smaller ... Test over 10 cables types using RJ45, USB B/B3, USB A/A3, USB C, ...

The Arduino Cable Tracer has been created using an Arduino Mega 2560 board with its IO pins connected to USB-A, USB-C, Micro-B, and Mini-B ports.

In about 25 years I don’t think I’ve ever had a USB A-B cable fail. ... * Problem: Change the Arduino Uno’s ancient USB B Female connector to Micro USB Female. No custom PCBs allowed.

USB requires negotiation to pass more than 100 mA, or measuring the resistance between the D wires to identify a high power charger. A power-only cable is ironically only able to pull the lowest ...

In the case of the Arduino Nano, a mini-B USB cable is required. The power source, on the other hand, can be a powerbank, a phone charger, or even your computer — anything that generates 5V and ...

Meanwhile, the Arduino Mega is getting the same USB chip along with an ATMega2560 processor with twice the memory. Right now only 128K is available, but that's a software limitation and they're ...
