Description
The ANT3-M24LR04E antenna reference board is a ready-to-use PCB that features an M24LR04ER Dual Interface EEPROM IC connected to a 4.7 µH SMD inductor acting as an RF antenna on one side, and to an I2C bus on the other side. The ANT3-M24LR04E antenna allows system designers to evaluate the M24LR04E-R performance and capabilities, and to get started with their design. The ANT3-M24LR04E Gerber files can be downloaded from http://www.st.com.
