Making IoT hardware simple

The Internet of Things (IoT) is revolutionising many aspects of our working and personal lives.

At ControlBits we're dedicated to 'making IoT hardware simple' by providing off-the-shelf hardware, open source software and fully supported hardware development kits.


Our first product, the 'EMIT' (Environmental Monitoring IoT) development kit successfully completed its crowdfunding on the 3rd September 2020 and we're making the final preparations to ship our first batch of product in the next few days!
