What is the NCD IoT Interface?
The NCD IoT Interface provides users with a means of changing or upgrading the IoT communications technology as new technologies emerge. The NCD IoT Interface is directly compatible with Particle Photon for WiFi communications, Electron for Cellular Communications, Bluz for Bluetooth. Optionally, adapters may be installed to provide a direct interface to Arduino Nano, Micro, USB, PyCom WyPy, Onion Omega, Raspberry Pi, and much more. The NCD IoT interface allows you to re-use your hardware so it never becomes obsolete! Based on I2C communications, the NCD IoT Interface uses only 2 GPIO lines of your microcontroller, freeing the rest of your CPU for other tasks.
nodeLynk™ IoT Device Expansion
This is a IoT Device which accepts a common processor and provides on-board sensing or control capabilities. This IoT device may be expanded to include additional hardware functionality using nodeLynk Expansion Devices. The NCD IoT socket found on IoT devices is capable of directly handling NCD ESP8266 and ESP32 series processors as well as Particle Photon and Particle Electron. We also manufacture many adapters for the NCD IoT socket for Arduino Nano, Micro, and Feather microprocessor modules. Between the socket is a nodeLynk connector, which is used for I2C Expansion.
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.
Unlimited I2C Expansion
Based on our plug-and-play nodeLynk I2C interface standard, all NCD IoT devices are equipped with a nodeLynk I2C expansion port, making it easy to expand to a wide variety of sensors, current monitors, relay controllers, PWM controllers, and much more! We are always designing new nodeLynk expansions for our plug-and-play nodeLynk I2C framework. We are dedicated to building a product line of interconnected devices to simplify all forms of automation. Re-use or upgrade your hardware in seconds by selecting the modules that best fit your needs, and chaining them together using the included nodeLynk I2C expansion cables!
