Product description: M24LR-Discovery
Development set based on dual interface EEPROM M24LR04E-R. It consists of two ready-to-use boards that can communicate with each other using the I2C bus or track radio RFID frequency13.56 MHz, NFC is used in mobile phones. Board M24LR equipped with an LCD display and a microcontroller with sensors in versions with low energy consumption. Thanks to that, the whole system can work wirelessly (inductively).
