I2C Shield for Arduino Uno
The I2CAS1 is a +5V I2C Expansion Shield for the Arduino platform.
This shield acts as a gateway to the entire NCD I2C product line, allowing limitless expansion possibilities. This shield could be the single most significant shield for your Arduino 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.
