M5Stack Stamp UWB Module
M5Stack Stamp UWB Module is an ultra-compact embedded UWB ranging module that supports castellated-hole SMT mounting. This module integrates the low-power QM33120W UWB transceiver, which is compatible with IEEE 802.15.4-2020 and IEEE 802.15.4z-2020 BPRF. The Stamp UWB module offers stable RF performance and operates on UWB Channel 9 with a center frequency of 7987.2MHz. This module supports TWR and TDoA positioning solutions for centimeter-level ranging and high-precision positioning. The Stamp UWB module features an SPI communication interface and supports 850kbps and 6.81Mbps wireless communication data rates. Typical applications include indoor personnel positioning, cargo and asset tracking, proximity detection, and robot navigation.
