DS2401 silicon serial number IC Each board has a unique 48-bit serial number 1-Wire interface 3.3V or 5V power supply
Unique ID click carries DS2401, an enhanced silicon serial number IC. It's a low-cost solution for providing a unique registration number to your design. No two are the same. The chip consists of a factory-lasered 64-bit ROM that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit family code.
It can be used for equipment registration, network node identification, or just a means to distinguish individual pieces from a production run (you could use the click for prototyping such a feature). It's also an excellent teaching tool for getting to know how 1-Wire communications work.
The DS2401 chip uses a single pin for control, address, data and power. The multidrop capability also allows for multiple DS2401 chips to reside on a single data line. The board uses 1-wire communications with your target board's microcontroller, either through a GP1 or GP0 pin (here in place of the default AN and PWM mikroBUS pins). The board is designed to use either a 3.3V or 5V power supply. Solder jumpers are used for these settings. They are set in the GP0 and 3.3V positions by default.
Note: The picture shows the board with through-hole headers. The board now comes populated with male pin headers already soldered for your convenience. The board's user manual has yet to be updated to remove the soldering instructions.
mikroBUS Click Boards Overview Click boards plug directly into a mikroBUS socket. mikroBUS is a specially designed plug-and-play pinout standard. The sockets are found on Clicker boards, the Flip & Click Arduino/Python-compatible board, the Quail board, these mikromedia shields, the Microchip Curiosity board, and development systems from mikroElektronika (V7 systems and later).
You also can connect Click boards to many other popular platforms via these adapters:
- PC — Click USB Adapter (MIKROE-1433)
- Arduino — Arduino UNO click shield (MIKROE-1581) or Arduino Mega click shield (MIKROE-1900)
- Raspberry Pi — Pi click shield (MIKROE-1512) or Pi 2 click shield (MIKROE-1879)
- BeagleBone Black — BeagleBone click shield (MIKROE-1596) or mikroBUS Cape (MIKROE-1857)
- STM32F3 Discovery — STM32F3 Discovery Shield (MIKROE-1447)
- STM32F4 Discovery — STM32F4 Discovery Shield (MIKROE-1481)
- Stellaris LM4F120 LaunchPad / Tiva TM4C123G LaunchPad — Click BOOSTER PACK (MIKROE-1363)
- Freescale Freedom — FRDM-KL46Z click shield (MIKROE-1795) or FRDM-K64F click shield (MIKROE-1794)
In addition, it is royalty-free to add mikroBUS to your own designs. Visit the mikroBUS Category to see the full line of Click boards.
