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!
Documentation
Adapter Types:
We have designed 3 types of adapters for Onion Omega to better suit the subtle size differences between controllers.* The vast majority of devices are compatible with the Type A adapter. Type B and C are for special-use cases. While Type C is also compatible with most devices, Type B will have fitment issues with many controllers, though it may be useful in certain circumstances.
Type A: Brings the Onion Omega to the front of the PCB with a bias to the right side, allowing taller components to peacefully coexist on the left side of the adapter.
Type B: Brings the Onion Omega to the front of the PCB with a bias to the center and slightly to the right, allowing taller components to peacefully coexist on each side of the adapter.
Type C: Keeps the Onion Omega 0.200″ from the front of the adapter, and is horizontally near center with a slight bias to the right.
*Please contact us if you are unsure of the adapter to use for a particular device. WE WILL CONTACT YOU IF YOU HAVE CHOSEN AN ADAPTER THAT DOES NOT FIT A CONTROLLER ON THE SAME ORDER.
IoT Interface Compatibility
NCD IoT Interface devices are designed to plug in to many popular IoT computing platforms. This allows the “brains” from other manufacturers to directly plug into our devices for easy plug-and-play operation. IoT interface devices use I²C as the underlying communications technology. The notes below will guide you into plugging 3rd party IoT technologies into our devices, we will highlight any adapters that may be required in this section. Please note that all IoT Interface Devices act as a I²C Master Device, and may be expanded by connecting to any of our Cross-Platform nodeLynk I²C Slave Devices using the nodeLynk I²C Output.
NCD IoT Interface Direct Connection
The following devices directly plug into NCD IoT Interface controllers without a adapter.
- Particle Electron
- Particle Photon (Particle.io)
- Bluz Module (Bluz.io)
- ESP8266 Module
If using a Particle Photon or Particle Electron communications module, the PKFR Key Fob Receiver overlay shield may be used to add long-range wireless Key Fob remote control to the communications module.
