Nguyen Hoan Hoang from I-SYST inc, Canada has developed a miniature wireless MCU module based on nRF52840 which can sit on your fingertip.

He specializes in Wireless connectivity, Smart Sensor & IoT Solutions. Prior to this module, he has already designed another module called BLYST Nano. I am sure many of your have already read about it.

So, what is new in this BLYST840 module?

It’s a feature-rich but miniature and ultra-low-power SoM to make it easy to use in your IoT Project.

See a small introduction video below:
