The Localization Board with MCX W72 is an evaluation kit for demonstrating Bluetooth® Channel Sounding for IoT applications. This board consists of two monopole on-board PCB antennas and an RF switch supporting antenna diversity, an integrated programmer/debugger and a mikroBUS™ header to easily add expansion boards. It provides the most suitable development and evaluation platform for the Bluetooth LE Channel Sounding feature, as it supports Antenna Switching by default. This Localization Board is based on the MCX W72 IoT multiprotocol MCU, and is ready for production channel sounding designs. The MCX W72 MCU is qualified against the Bluetooth Core 6.0 specification.
