Introduction
The STEVAL-USBI2CFT is a versatile USB-I2C bridge for communication and programming of ST wireless charging IC, and evaluation boards, with the STSW- WPSTUDIO software.

Software installation
The STEVAL-USBI2CFT is based on the FT260Q, USB HID to I2C bus convertor. The
FT260Q does not require any additional software drivers.
The Windows operating system automatically installs the necessary driver after
the first USB plug-in.
Hardware connection
Before starting the communication with a wireless receiver or transmitter, the
dongles shall be correctly connected to each other. Connect GND of bridge with
GND of evaluation board, continue with connecting of SDA, SCL, and INT.
The STEVAL-USBI2C board includes an internal level-shifter.
The voltage level can be changed soldering one of the soldering bridges.
The voltage can be set to 1.8, 2.5 or 3.3 V depending from what solder bridge was soldered.
Ensure that the target evaluation kit is connected to the USB-I2C bridge and the bridge is connected to the PC with the STSW-WPSTUDIO software installed.
The STSW-WPSTUDIO can connect a maximum of two USB-I2C converters, allowing PTx and PRx to be evaluated simultaneously.

| Part number | PRx/PTx | Description |
|---|---|---|
| STEVAL-WBC86TX | PTx | 5 W PTx for general application |
| STEVAL-WLC98RX | PRx | Up to 50 W application |
| STEVAL-WLC38RX | PRx | 5/15 W PRx for general application |
| STEVAL-WLC99RX | PRx | Up to 70 W application |
Interface description
The STSW-WPSTUDIO main interface consists of three main sections: the top
menu, the side menu bar, and the output window.
The side menu bar selects the output in the output window.
