Arduino ASX00074 Portenta UWB Shield

Arduino ASX00074 Portenta Ultra-Wideband (UWB) Shield is a double-sided 70.1mm x 37.5mm board with the Truesense DCU150 UWB module overhanging the bottom edge and two high-density connectors on the top side of the board. The Arduino ASX00074 integrates with the Arduino Portenta C33 board and functions as a base station for two-way ranging and real-time location services (RTLS). The DCU150 module incorporates the NXP Trimension™ SR150 UWB integrated circuit (IC), three embedded PCB antennas, onboard power management, clock control, filters, and peripheral components. With 1.8V_DC to 3.3V_DC level shifters and the dual high-density board-to-board connectors, ASX00074 plugs directly into the Portenta C33 board.
