It’s a huge headache and one that [TechKiwiGadgets] hopes to solve with the Arduino Cable Tracer. The tracer works with USB-A, Mini-USB, Micro-USB, and USB-C cables to determine whether ...

The Arduino cable tester ... USB and RJ45 network cables and will identify the exact wiring configurations as well as diagnose broken wiring, and plug pin connections. Test over 10 cables ...

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.

The next three-pin connector (J1) is for an external DC digital voltmeter (DC DVM). Aside from these, there’s nothing else — it’s a pretty straightforward design. If you replace the resistors R1 and ...

If the jumper is in position 2-3, the voltage from the Arduino (USB or hollow socket) is fed to the red pin headers. Note that then only a low current carrying capacity is possible, as is otherwise ...

* Problem: Change the Arduino Uno’s ancient USB B Female connector to Micro USB Female. No custom PCBs allowed. * Solution-1, USD $4.49 total to modify ten Unos ($0.45 each): ...
