USB 測試儀

USB has become the core of many projects. In my experience I've found it to be troublesome to test USB voltage levels and current usage using a breadboard. They usually consist of holding wires attached to the DMM’s test leads, making it difficult to get solid readings. The USB Tester will make it much easier to monitor any USB project’s power source.

 

As part of the USB spec, you are limited to 500ma, so you want to monitor how close you are. Most people use USB hubs, both powered and unpowered, and with many devices connected, you can end up with less than 5V which can cause havoc on you projects. The USB Tester will make it a snap to monitor voltage levels and current usage without having to re-wire your breadboard. Just connect to your oscilloscope or DMM test leads, and you’re good to go! The USB Tester has both banana clip sized drills and standard 0.1” headers. When you are not testing current you can add a jumper for normal operation. The USB D+/D- pins are also broken out so you can monitor those on an oscilloscope, or for USB sniffing.

 

The USB Tester PCB size uses Dangerous prototypes Sick of Beige standard DP5031 so that it can be used as a base. You can find an acrylic base here.
