The UWB Ultra Wideband long distance Positioning（300m) Module.
ULM3-PA is based on the latest DW3000 series chip.
The core UWB module of ULM3-PA is an official Decawave DW3210, and the MCU is STM32F103CBT6 (or GD32F103CBT6).
ULM3-PA can be used for precise ranging, indoor positioning, and other high-speed data communication applications. It also integrates an OLED display, making it easy to use with its small size and high precision.
For positioning applications, ULM3-PA can be used as an anchor or tag, and multiple ULM3-PA modules can form a complete TWR positioning system (RTLS1). It should be noted that a minimum high precision positioning system with 3 anchors and 1 tag can be achieved by 4 ULM3-PA modules, while a typical high precision positioning system with 4 anchors and 1 tag can be achieved by 5 ULM3-PA modules.
