I2C-Assemblies

In this section you will find interesting assemblies around the I2C bus.



  • I2C-PC-Interface

    These modules provide an interface to the I2C slave and a PC or other master example Raspberry-PI.

  • I2C Digital Input-Card

    With the input cards digital signals can be read.

  • I2C Digital Output-Card

    With the I2C-output digital consumer can be activated or switched.

  • I2C-Analog-Cards

    With I2C analog cards, it is possible analog signals (voltage, current, temperature) can be read and analog devices can be controlled.

  • I2C DIN rail modules

    These modules all have a dimension of 42 mm x 63 mm.


    They can be very easily installed with the Wago mounting frame for small boards on a DIN rail.



  • I2C-433 MHz transmitter

    Control standard radio outlets via the I2C bus

  • I2C WLAN module

    Communicate via WLAN with the I2C modules

  • I2C-Sensors

    In this section you will find sensors that can be operated directly on the I2C bus.

  • I2C test boards

    With our Breakout Boards I2C modules can be tested without much effort.

  • I2C-Mux / Switch

    With I2C switches you to bus segments individually.

    With I2C multiplexers to slaves with the same address can be addressed on the bus.

  • I2C-Repeater

    I2C-Bus Level Translating between 3,3 V and 5 V

  • I2C-Chipcards

    Here you will find I2C chip cards and readers or contacting units.

  • I2C-LCD-Display

    Our LCD displays can be addressed directly via the I2C-bus or RS232 serial interface.

  • I2C-ICs

    I2C ICs and programmed PICs for our circuits and kits.
