ams AG - global leader in the design and manufacture of high performance analog ICs (integrated circuits)


The USB-I2C dongle is a small device with a form factor much like a USB flash memory. It can be inserted in a PC and then allows the PC to act as an I2C master.

The dongle is used in the evaluation kit of several environmental sensors of ams.

Here you find a user manual, the Windows driver (Windows 7 and 8, not needed for 10), and the firmware for the (micro controller on the) dongle.


The user manual of the USB-I2C dongle describes installation (Windows, Mac, linux), hardware (power, pinning, firmware button), concepts (register and raw model, configuration, transactions, traces), and finally detailed usage (first commands, UART conventions, command reference).


The USB-I2C dongle is plug and play for Windows 10 and Linux. Windows 8 and 7 do require a driver.


The micro controller on the USB-I2C dongle is pre-programmed with a firmware image. When features are added, later versions are published here.
