What is OBJEX Link?

OBJEX Link is a modular IoT board. It is designed to develop IoT devices that are easy to repair and recycle. It's perfect for a wide range of uses: Smart Home & Cities, IIOT, Everyday things & Wearables, Predictive Maintenance, Agriculture Automation. It can also be used for rapid prototyping and developing research and robotics projects, with the right module, you can extend the possible uses of the board.

The compact form factor and board design ensure easy use and maintenance of the board. The architecture of OBJEX Link is composed of two parts, the first is the mainboard (OBJEX Link) and the second is the module allows for easy customization and interfacing with hardware compared to other IoT boards.

Example of use

This is an example of a smart device developed with OBJEX Link v1.7-C3 RISCV. This device detects the temperature is the humidity of an environment, the data collected by the sensor is sent to a cloud server.

Using a simple App it is possible to read the values of temperature and humidity detected by the sensor. The autonomy of the battery can guarantee up to one year of use, depending on the number of measurements taken daily.
