Raspberry Pi Zero Shield with Outward Facing I2C Port

  • Provides a Level-Shifted +5V I2C Port
  • Non-invasive Outward Pointing Connector
  • 40-Pin Pass-Through Connector
  • Allows Connection of External Sensors and Controllers
  • Adds Limitless I2C Device Expansion Options


Unlock a world of expansion controllers for use with the Raspberry Pi Zero using the PZI2C expansion.

The PZI2C provides a 5 Volt I2C expansion port, allowing your Raspberry Pi Zero to connect to an ever-growing array of expansion devices from ControlEverything.com.

Connect sensors for light level monitoring, gas level detection, temperature and humidity monitoring, as well as many types of motion, acceleration, and direction sensors.

Connect our entire array of relay controllers, digital I/O expanders, PWM controllers, and current monitoring devices to the Raspberry Pi Zero with a simply daisy-chain interface.

The PZI2C provides a true level-shifted +5V I2C communication port to the Raspberry Pi Zero, making it one of the most important expansions available. The PZI2C allows you to expand your Raspberry Pi Zero into the world of hardware so you can focus on software. The PZI2C includes a 40-Pin pass-through connector, allowing other expansions to safely stack above this device, making it a truly non-invasive upgrade.

Companion - Purchasing Limits Apply

These products are sold at a low price in an effort to help our customers gain connectivity to our product line.  Companion products are intended to be paired and used with other products we manufacture, as they perform no useful function on their own.  Any orders that contain only companion products will be canceled to prevent short supply.  Most notably, products found on our web site for $5.95 or lower are typically defined as companion products (though there are a few exceptions).

As a general guideline, we allow one companion product to be purchased for every device with a silicon chip that has an I²C start address, with a maximum of 3 companion products of a single part number.  For instance, you can purchase a Raspberry Pi I²C adapter and a Temperature sensor without any problems.  You can purchase 3 I²C adapters and 3 temperature sensors without any problems.  You can purchase 3 I²C adapters and 20 temperature sensors, but no more than 3 I²C adapters of the same part number. 

Order Limits:

  • We will allow up to ONE companion product without any silicon based controllers per order.
  • We have placed a maximum quantity limit of 3 pieces per companion part number.

Please help us balance the production costs of our low-cost devices and support our company by purchasing devices to go with our companion products, this is the only way we can stay in business.
