The I2CAS1 is an Arduino uno I2C shield +5V I2C Expansion Shield for the Arduino platform.
This shield acts as a gateway to the entire ControlEverything.com I2C product line, allowing limitless expansion possibilities. This shield could be the single most significant shield for your Arduio ever made simply because of it's extreme low cost and broad expansion possibilities.
Integrated 4.7K pull-up resistors make it an ideal I2C master device. Pass-though design allows you to non-invasively sandwich this shield between other Arduino shields without sacrificing compatibility or expandability. This I2C expansion port is compatible with our entire range of I2C devices, including relay controller, sensors, and various mini modules, making expansion of the Arduino quick and easy, regardless of your application requirements.
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.
- 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.
