The PCA9306 I2C Level Shifter is a complete level and power shift solution for I2C communications.

The input side of the PCA9306 accepts a I2C communication voltage as well as a power supply voltage from 0.3 to 5VDC. The output side of the PCA9306 provides a regulated 5VDC voltage and 5V I2C communications, ideal for use with the entire ControlEverything.com product line.

This device uses a Texas Instruments power conversion chip to raise the incoming voltage from .3V to 5VDC at 200ma.

The PCA9306 handles I2C data level shifting. This device can be used to adapt low voltage I2C communications from embedded systems such as the Intel Edison to our 5V power and communications standard.


This is a general purpose I²C device compatible with all computing platforms and IoT technologies, including Raspberry Pi, BeagleBone, Arduino, Particle, BridgeX5, and many more.  All ControlEverything.com devices support a strict +5V I²C Bus standard.

Mini Modules

Our mini modules provide a standardized footprint to simplify the design of your project, and allow for a smaller form factor without sacrificing the plug-and-play  ease of use that our product line affords.

All I²C Mini Modules are designed to operate at 5VDC. Using a convenient quick connect 4-Pin plug, devices can be daisy-chained onto the I²C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application.

Pull-up resistors are included with all ControlEverything.com master devices. If you are wiring in your own I²C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.

All mini modules are 50.8 x 31.75 mm.
