The Unique ID Click Board™ is a low-cost accessory board that includes a DS2401 enhanced Silicon Serial Number IC. It provides a unique registration number to the hardware design. Two Unique ID Click Boards™ might look alike on the outside, but each Click Board™ features a unique 48-bit serial number, which distinctively identifies the device in the world of mass-produced electronics. The Unique ID Click Board™ is also an excellent teaching tool for a user to understand how 1-Wire communications work. It uses 1-Wire interface for communication with the target board microcontroller, either through a GP1 or GP0 pin (here in place of the default AN and PWM MikroBUS pins). The power for reading/writing the device is derived from the data line itself with no need for an external power source. The multidrop capability also allows for multiple DS2401 chips to reside on a single data line. It is designed to use either a 3.3V or 5V power supply.
The Unique ID Click Board™ is an ideal choice for equipment registration, PCB identification, establishing network node ID, and other similar purposes.
