This project consists of developing a simple device in order to count pulses and sending a report to a backend using NB-IoT.

The main requirements of the whole system are:

I’ve selected this module BC66 by Quectel with the following features:

We were able to design a small circular PCB of 60 mm with everything necessary for working properly: NB-IoT module, microcontroller, antenna and battery. I was the project manager in charge of the whole project: electronic design, schematics, PCB, antenna adaptation and power consumption approach.

Used technologies: C, NB-IoT, Antenna Design and Altium Designer.
