Perfect for connecting any development board, microcontroller, mobile phone, or other device to your computer or charger. Can be used to monitor your project or as a current meter. Quarter not included 🙂
Plug it into a USB port the display will show the voltage on the USB power pins. Once a device is plugged in, it will display the current draw in milliamps. The only down side is that once the device starts charging, the display will not show the voltage anymore, just the current draw.
