MaUWB_DW3000 Chipset

Ultra-wideband (UWB) is a short-range, wireless communication protocol that operates through radio waves, enables secure reliable ranging and precision sensing, creating a new dimension of spatial context for wireless devices. It is widely in indoor position/ tracking. In field application, the most problem of UWB is the signal mutual conflicts/interference, that when there multiple anchor& tags exists.

That is why the MaUWB module exists, this module is designed specially for indoor distance measurement between multiple anchors& tags, based on STM32 controller and DW3000, with antenna/PA/LNA on board, it features:

• - AT Command& Serial Output: This module runs Makerfabs default firmware that output directly distance measurement results among multiple anchors(max 8)& tags(max 64), without users to deal with the complicated spec/factors in using them. Users can also set simply setting via AT command, such as the antenna delay/sleep;

• - Long range: With on-board PA/LNA, the max distance at least 300m
• - Roles Setting: each MaUWB can be set as anchor or tag by AT command
• - Easy to work with any controller: with it simple output, it can work with any controller such as Arduino/Raspberry PI..

Spec:

• 1) Comply with IEEE802.15.4-2011 ultra-wideband standard;
• 2) Easy to integrate without additional RF design;
• 3) Support CH5 (6489.6MHZ) RF band;
• 4) Strong resistance to multi-path fading;
• 5) Two modes of data transmission rate of 850kbps and 6.8Mbps;
• 6) The maximum packet length is 1023 bytes, which meets the application requirements of high data volume exchange;
• 7) The system supports 8 Anchor 64 tags.
• 8) The module supports free configuration of refresh rate, up to 100Hz;
• 9) Module serial port communication baud rate 115200;
• 10) Module (Tag) deep hibernation working current as low as 35uA, working current 34mA;
• 11) Support AT command;
