UWB650:High-Precision Ranging & Indoor Positioning UWB Module AES128 Encryption

UWB650:High-Precision Ranging & Indoor Positioning UWB Module AES128 Encryption

UWB650 module, launched by NiceRF, is a wireless communication module based on Ultra Wide Band (UWB) technology and compliant with the IEEE 802.15.4-2020 Standard protocol. Developed from the UWB3000F27, the UWB650 module features a high-power 0.5W amplifier chip. Users do not need to design any circuits, as the UWB650 module includes the wireless communication module and related circuits, integrated with ESD protection devices to provide effective ESD static protection. The UWB650 module combines data communication, two-way ranging (DS-TWR), and three-point planar positioning functions of UWB technology into one module. Users can easily utilize these functions through the UART interface on the module without the need for additional design and development.
