USB multimeter for voltage and current at USB port - secure Arduino! - Budget
- Item no: F23108573
- Weight: 0,02 kg
This component can be used to measure the device output voltage and the current intensity at the USB port of the computer. In this way, it is possible to check how high the current strength is in a setup with Arduino microcontrollers, in order to protect the PC from too high a current strength if necessary. It can also be used to check whether a current is flowing when a terminal device is being charged via the USB port.
Xcessor USB Tester - Charger Doctor is a portable charging tester that can detect any USB charger such as PC USB, mobile USB, home charger and car charger. High quality testing and troubleshooting tool to check the performance of USB power sources. Suitable for testing and monitoring USB ports on your computer, cell phone or mobile power bank.
