Description
The ANT7-T-25DV64KC antenna reference board is a ready to use PCB that features
an ST25DV64KC connected to a 14 mm x 14 mm, 13.56 MHz etched RF double
layer antenna on one side, and to an I²C bus on the other side.
This evaluation board allows system designers to evaluate the ST25DV64KC
performance and capabilities, and to get started with their design.
To demonstrate the energy harvesting function the ANT7-T-25DV64KC can be used
in conjunction with the ST DEMO-CR95HF-A board.
The board design and the Gerber files can be downloaded from www.st.com.
If externally powered, supply has to be safety extra-low voltage (SELV) according to
EN60950-1 (< 5 V, < 15 W). The power supply is classified ES1 (electrical energy
source class 1), PS1 (electrical power source class 1) according to EN62368-1.
