Description
The ROBOT-M24LR16E-A is a ready-to-use PCB that features an M24LR16-R dual interface EEPROM IC connected to an I²C bus and a 20 mm x 40 mm 13.56 MHz etched RF antenna. It also features two LEDs, powered by the M24LR16E-R V
The ROBOT-M24LR16E-A has three functions:
Switch in the “LED” position: the robot demonstrates energy harvesting by powering the LED when a sufficient magnetic field is captured.
pin and an output connector.
OUT
Switch in the “V
” position: the energy
OUT
captured from the electromagnetic field is used to power an external application through the V
OUT
pin.
RF WIP/BUSY function: for the RF WIP/BUSY pin of M24LR16E-R, please refer to the M24LR16E-R datasheet for further details.
To demonstrate the energy harvesting function, the ROBOT-M24LR16E-A can be used in conjunction with ST DEMO-CR95HF-A demonstration board.
