Introduction:
HMC Holding has developed FirstWatch CPU (FWCPU) which will use for Electronics safe and access controlproducts. FirstWatch CPU contains 2.4GHz and 915 MHz Radio. 2.4GHz radio is used for communication over Bluetooth5.0LowEnergyaand915MHzradioisusedforcommunicationwithremotecontrol. Itspoweredby4.5Vto10VDCvoltage. 2. Block Diagram:
