OBJEX Link v1.5
OBJEX Link v1.5 is the default version of the series. This version of OBJEX Link is designed to provide high computing power. With the compromise of slightly increasing power consumption. The board is very compact and can be used for various IoT applications and more. It is possible to install two M0 modules or one M1 module.
IoT Applications: Smart Home & Cities, IIOT, Predictive Maintenance, Agriculture Automation.
It's also ideal for rapid prototyping, advanced research projects, and robotics projects.

OBJEX Link v1.5 is currently an experimental prototype, but all components used are RoHS compliant.
OBJEX Link v1.5 does not yet have all the certifications needed for mass sale. Currently, only a few prototypes are distributed for testing and research purposes, and not for real use on IoT devices.
