45 mm x 75 mm flexible antenna reference board for M24LR04E-R Dual Interface EEPROM, Documentation purpose only

The FLEX-M24LR04E antenna reference board is a ready-to-use flexible PCB that features an M24LR04E Dual Interface EEPROM IC connected to a 45 mm x 75 mm 13.56 MHz etched RF antenna on one side, and to an I2C bus on the other side.

The FLEX-M24LR04E antenna allows system designers to evaluate the M24LR04E performance and capabilities, and to get started with their design.

To demonstrate the energy harvesting function, the FLEX-M24LR04E can be used in conjunction with ST DEMO-CR95HF-A demonstration board.

The application can be powered directly from the M24LR04E VOUTpin.

The FLEX-M24LR04E Gerber files can be downloaded from www.st.com.
