But don't they sometimes seem a little \u003cstrong\u003e\u003cem\u003eBIG\u003c\/em\u003e\u003c\/strong\u003e?!\u003c\/p\u003e \u003cp\u003eEnter \u003cstrong\u003esmôl\u003c\/strong\u003e, a new range of boards which are both small in size and small on current draw. It's a smôl world!\u003c\/p\u003e \u003cp\u003eYou might be wondering why we would make an NFC\/RFID tag peripheral board for smôl? The STMicroelectronics ST25FV64KC is a \u003cem\u003e\u003cstrong\u003edynamic\u003c\/strong\u003e\u003c\/em\u003e Near Frequency Communication \/ Radio Frequency Identification tag IC with 64Kbit (8KByte) of on-board EEPROM memory. It has an I\u003csup\u003e2\u003c\/sup\u003eC interface which the smôl processor board can use to read and write to the EEPROM memory. But the memory can also be read and written to over the RF link \u003cem\u003ewhile your smôl ecosystem is in deep sleep\u003c\/em\u003e! This means it is perfect for: contactless data storage and collection; and for configuration.\u003c\/p\u003e \u003cp\u003eLet's suppose you have assembled a small data logging system using smôl boards. It spends most of its time in deep sleep, waking up every few hours to take a reading. You want to be able to read the data logged by the system, but you don't want to have to connect a cable to your logger or have to wake it up to get at the data. The NFC\/RFID tag peripheral board is the perfect solution. The processor board can write the data into the tag's memory and then go back into deep sleep. You can then read that data with an app on your smartphone at any time!\u003c\/p\u003e \u003cp\u003eThe NFC\/RFID tag peripheral board would also let you configure your smôl logging system. Let's say you want to change the logging interval from 1 hour to 2 hours, but you don't want to have to connect a cable to your logger or have to wake it up to change the interval. Again, the NFC\/RFID tag peripheral board is the perfect solution. You can write the new configuration data to the tag using your smartphone. The processor board can then read the new configuration when it next wakes up!\u003c\/p\u003e \u003cp\u003eOur Arduino Library provides all of the methods you need to read and write the user memory, control the read and write permissions, alter the area sizes and apply password control. Not only that! We've included extra methods which will let you read and write \u003cstrong\u003eNDEF (NFC Forum Data Exchange Format) URI, WiFi and Text records\u003c\/strong\u003e which your smart phone can understand!

Designed to be both physically small and to have the smallest possible current draw, smôl is the perfect choice for applications like wildlife tracking or discrete long-term monitoring. smôl boards are designed to stack one on top of the other, using 16-way 0.5mm-pitch Flexible Printed Circuits (FPCs) to provide the interconnect from one board to the next.
