Adafruit FriedCircuits USB Tester v2.0

The USB Tester simplifies monitoring voltage levels and current usage in USB projects, eliminating the need for cumbersome methods like splicing cables. Ensure your connections are optimal as ports are limited to 500mA.

The tester integrates seamlessly with your oscilloscope or DMM using banana clips or standard 0.1” headers, providing reliable readings without re-wiring. Stay informed as connected devices may lead to voltage drops below 5V, potentially disrupting your projects.

Beyond typical voltage and current monitoring, the D+/D- pins are accessible for advanced tasks such as USB sniffing. The package includes an assembled PCB and a jumper for when current testing is not required. Simple, effective, and indispensable for USB troubleshooting.
