UWB650 module, launched by NiceRF, is a wireless communication module based on Ultra Wide Band (UWB) technology and complies with the IEEE 802.15.4-2020 Standard. It is designed using the Qorvo DW3000 UWB chip and integrates a high-performance RF power amplifier, MCU, general-purpose I/O interfaces, and ESD protection components. The UWB650 module combines data communication, ranging, and positioning functions in UWB applications, enabling remote communication, precise distance measurement/positioning, and hardware control via a serial interface.
