Arduino Micro Compatible I2C Shield

  • Provides a +5V I2C Port with 4.7K Pull-Ups
  • Non-invasive Outward Pointing Connector
  • Compatible with Overlay Expansions for Arduino Micro
  • Interface External Sensors and Controllers
  • Adds Limitless I2C Device Expansion Options


Use the Arduino Micro to take control of our complete line of devices with the AMI2C expansion.

The AMI2C provides a 5 Volt I2C expansion port, allowing your Arduino Micro to connect to an ever-growing array of expansion devices from

Connects 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 Arduino Micro with a simple daisy-chain interface.

The AMI2C provides a true +5V I2C communication port to the Arduino Micro, making it one of the most important expansions available. The AMI2C allows you to expand your Arduino Micro into the world of hardware so you can focus on software.

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.
