STMicroelectronics ST715PUR / STM32F031F4P6 | Demoboard STDES-USBPWRMT1

Beschreibung

The STDES-USBPWRMT1 is a measurement device that can be inserted between a USB Type-C™ power source and a USB Type-C™ power sink device. The STDES-USBPWRMT1 power meter includes a USB Type-C™ receptacle connector on one side and a USB Type-C™ plug on the other side.The power meter embeds a shunt resistor that is inserted on the USB Vbus lines and enables the measurement of the current flowing through the dongle.All data lines are carefully routed from the input of the power meter to the output, so that transmitted data are affected as little as possible by the insertion of the power meter.The bright display provides an accurate information of the USB port voltage, current, resulting power, and current direction.This type of information can help the user to understand which charger is more efficient, in order to charge a device faster, or simply to visualize the power transfer from one device to another.
