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.

nodeLynk™ Master Adapter

This is a nodeLynk Master adapter.  nodeLynk Master adapters speak to a chain of nodeLynk devices using I2C communications.

What is nodeLynk?

Chain expansion devices using nodeLynk. Connect a wide variety of accessories to expand the capabilities of a nodeLynk compatible controller.  Use nodeLynk to add Relay Controllers, Sensors, PWM Drivers, Displays, and a wide variety of 4-20mA, 0-10V ADCs and DACs, as well as a wide array of TTL & Isolated GPIO devices.  All nodeLynk devices use I2C communications to chain devices together.  nodeLynk is an easy way to expand functionality without soldering.  nodeLynk allows expansion in seconds so you can focus on your software and firmware development.
