Different SOC multiprotocol model Nordic Semiconductor is a company that specializes in ultra-low power performance wireless systems on a chip (SoC) and connectivity devices . It will produce several models of nRF SOC that can be used in our application, but we will choose just the most compatible and efficient SoC that ensures the good functioning of our system, so we will study and see the different specifications of some SoC, and here is the descriptive table of each model. BT module module BT832F/BT832AF BT832X BT840F BT840 SoC nRF52832/810 nRF52832 nRF52840 nRF52840 BT range,1 Mbps, LMPI 760 meters 1140 meters 1000 meters 150 meters BT range, 125 Kbps --- --- 2300 meters 320 meters Peak current RX 5.4 mA --- 6.4 mA 6.4 mA Peak current TX ...
