| - | Nordic Semiconductor is a company established in Norway that develops and produces exciting electronic elements capable of transmitting data with radio signals. Among other advanced chips, their portfolio includes the nRF52 family of SoCs, which support low-power radio communication with chosen popular protocols, including Bluetooth Low Energy, ZigBee, NFC, Matter and Thread. They achieved high popularity due to the low power consumption possible by implementing an advanced, adaptive power management system. There are a few versions of chips which support different combinations of protocols. The simplest nRF52805 supports BLE only, while the most advanced nRF52840 is a fully multiprotocol chip with all previously mentioned standards support. | + | Nordic Semiconductor is a company established in Norway that develops and produces exciting electronic elements capable of transmitting data with radio signals.
