If you have any questions, please feel free to contact us. Paradisetronic.com Your Store for DIY Electronics Adafruit ST25DV16K I2C RFID EEPROM Breakout, STEMMA QT / QwiicThis RFID tag is really unique: it works with cell phones just like other RFID tags, but can also be reprogrammed via I2C. The tag is displayed as an ISO / IEC 15693 chip (13.56 MHz) that can be read by smartphones and tablets. This can be of interest in situations where a tag is needed that can be dynamically rewritten when connected to a controller. For example, Adafruit carried out a test in which a microcontroller wrote different URLs every few seconds and the mobile phone recognized the different URLs one after the other.Please note that the popular Hobby RFID / NFC controller PN532 does not support ISO15693 and ST25DV tags cannot be used! Adafruit has successfully tested the readout of the tag with both Android and iOS devices. In addition, the main memory of Arduino boards with a classic ATmega328 microcontroller is not sufficient for control purposes, please use a board with, for example, a SAMD microcontroller such as the Metro M0. Instructions for commissioning the tag can be found at Adafruit: https://learn.adafruit.com/adafruit-st25dv16k-i2c-rfic-eeprom-breakoutEach board is delivered assembled and tested. The existing STEMMA QT resp. Qwiic connection can also be used for prototyping on the STEMMA QT adapter cable can be used.Technical details:I2C interface1 MHz protocolUses multiple I2C addresses 0x2D, 0x53 (user memory) and 0x57 (system memory)Supply voltage: 1.8 V to 5.5 V.Contactless interfaceBased on ISO / IEC 15693NFC forum type 5 day, certified by the NFC forumSupports all ISO / IEC 15693 modulations, encodings, sub-carrier modes and data ratesCustom fast read access up to 53 kbpsProduct dimensions: 31.7mm x 25.3mm x 4.6mm This RFID tag is really unique: it works with cell phones just like other RFID tags, but can also be reprogrammed via I2C.
