Hardware
It features the following connectors :
- USB-A male ( USB 2.0 only )
- USB-A female ( USB 2.0 only)
- USB-C male
- USB-C female
- USB-microB female
A CH573F MCU is responsible for performing all the measurements and managing the user interface.
A small SOIC-8 IC (marking BP0D608-68A2) handles the Bluetooth communication (both RFCOMM and BLE).

Protocol
The device communicates through serial-over-Bluetooth (RFCOMM), appearing under the UC96_SPP name, and BLE, under the UC96_BLE name. The same protocol is used both on the BLE and Bluetooth link.
The manufacturer provides an app named "E_Test" for Android and iOS, but no protocol documentation, although it appears that the protocol has been fully reverse-engineered [2].
