Description
The ANT3-M24LR04E antenna reference board is
a ready-to-use PCB that features an M24LR04E-
R Dual Interface EEPROM IC connected to a
4.7 µH SMD inductor acting as an RF antenna on
one side, and to an I
2
C 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
