FNB48S Bluetooth USB Tester - Voltage and Current Meter

The FNB48S Bluetooth USB Tester - Voltage and Current Meter is a multi-functional protocol capacity testing tool. It integrates USB-A, Micro-USB, Type-C interface with a 1.77-inch high-resolution display, external 16-bit ADC, using PD protocol physical chip, can measure voltage, current, power, capacity, charging protocol, curve waveform, etc. It provides real-time monitoring.

Application

Note: For Bluetooth, the application only supports Android 5.1 or later, BT 4.0 or later, and temporarily does not support iOS. Since the device uses a BLE BT module, you cannot connect to the fnb48s through the system settings; you need to search and connect in the app.
