Energy harvesting
In chip M24LR64E-R embedded function of energy harvesting allows to wireless power supply of devices with low power consumption (max. 7mA), when antenna of module is placed enough near from transmitter antenna (which use CR95HF chip). Power supply with harvesting energy is activated with using jumper “Harvesting Power”. Indicator starts periodically blinking with D2 LED, when on line +Vhr appears harvesting voltage from RF track.
