Mercury System, the HW/SW development system for IoT and Connectivity applications developed together with our collaborator Francesco Ficili, is now available on OpenStore.

The system uses various type of electronic boards (logic unit, modems, slave boards equipped with sensors and actuators, power boards…) and a complete SW framework to allow the realization of IoT and Connectivity applications. Scalability, expandability and ease of use are key factors and are allowed by the use of a heterogeneous set of components that allow to assemble the system like a construction made with LEGO© bricks.


The board set which composes the system is made up by the following “families”:
Base Board (BB): It’s the “brain” of the system and contains the main logic unit as well as different communication buses and connectors to interfaces the slaves. It also contains a simple power supply system and a recharge unit for a single LiPo cell (it can satisfy the power requirements of simpler systems). It can exist in different variants, depending on the employed microcontroller unit.
Modem Board (MB): it’s the board that allows network connectivity. It can exist in different variant, depending on the network interface (GSM/GPRS, Wi-Fi, BT, Radio…). It’s interfaced to the Base Board with a dedicated communication line.
Power Board (PB): it’s the board that allows to satisfy the particular power requirements of the system, when it’s necessary. They can vary, depending on the particular power requirement to satisfy (high power, solar harvesting, piezo harvesting, etc.).
Slave Board (SB): these are the system’s peripherals, and they vary depending on the specific mounted sensor or actuator. Typical examples are SBs with relays, temperature sensors, RGB LED controllers, servo controllers, accelerometers, etc. They communicate with the BB with I2C or UART channels and a dedicated command set.
Expansion Board (EB): these are the boards that allow planar connection of Mercury System. There are variants which can contains Displays, battery socket, etc.
Brain-Less Board (BL): these are the controller-less boards. They in general contain really simple sensors or actuators that don’t need the bus interface. There are meant as an alternative to slave boards for cost-sensitive applications.

Slave Boards and Modem Board are provided pre-programmed with a FW which implements a dedicated command set for a high-level management of the board, while the Base Boards are provided with a SW framework which encapsulates all the low-level services (operative system, device drivers, system services, etc.), leaving to the user the development of application level logic only. Moreover, the Base Board comes with an USB bootloader, so it can be programmed without the need of an external programmer.

The system allow to develop various types of applications, check our Youtube channel to see some of them:

– Bluetooth Moodlamp:
– GSM/GPRS Intrusion detector:
– IoT Meteo Station:
– Bluetooth Controlled Rover:
– Irrigation System with BT interface:

Here is a short presentation of what the system is and what allow you to do:
