The MCP9805 is a digital temperature sensor and a memory module designed to meet the JEDEC for Mobile Platform Memory Module Thermal Sensor.

This device provides an accuracy of ±1°C from a temperature range of +75°C to +95°C. The MCP9805 comes with user-programmable registers that provide flexibility for dual in-line memory module (DIMM) temperature-sensing applications.

This device also allows the user to set the Event output signal polarity to notify the user when the temperature changes beyond the temperatures specified.

All I2C Mini Modules are designed to operate at 5VDC. This Mini Module includes on-board power regulation and PCA9306 I2C level shifting circuitry to adapt to our 5V I2C standard. Using a convenient 4-Pin plug, devices can be daisy-chained onto the I2C Bus, eliminating the need for soldering. Plug together all the pieces you need for your next automation application.

Pull-up resistors are included with all Dcube Store master devices. If you are wiring in your own I2C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.

All I2C Mini Modules include a I2C Cable.

nodeLynk Device

This is a nodeLynk device, it will require a nodeLynk Master Adapter for proper operation.  nodeLynk devices plug into Master microprocessors to easily add hardware sensing and control capabilities.

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.

Plug and Play Connectivity

nodeLynk I2C devices will plug in to any available nodeLynk I2C Output.  This includes just about everything we make in the Dcube IoT Category, including all Dcube IoT devices.  We also manufacture a wide range of I2C adapters that make it easy to plug nodeLynk I2C Devices directly into most computing platforms.  nodeLynk I2C Interface adapters are available for Arduino, Banana Pi, BeagleBone, Bluz, ESP8266, Onion Omega, Particle Photon and Electron, PyCom, Raspberry Pi, 2, 3, and Zero, and Windows.  We are always working to add new platform support for nodeLynk I2C devices.  nodeLynk I2C Interface devices are compatible with just about everything in the microcontroller industry.
