The XM132 is an integration-ready low-power module with outstanding system cost, optimized for use cases such as presence detection and contactless monitoring of tank levels. With a solderable design featuring a land grid array and software adapted for specific use cases, cost and time-to-market are streamlined.

The XM132 Entry Module integrates the A111 pulsed coherent radar sensor with a 32-bit 64 MHz Arm® Cortex® M0+ MCU, the STM32G071CBU6 from STMicroelectronics, with 128 KB of Flash memory and 36 KB of RAM. The module supports a single supply operating voltage range from 1.8 V to 3.6 V.

For a quick and easy start, use the evaluation board XE132, which has the XM132 entry module soldered to it. The XE132 has support for UART communication over USB, which enables a straight-forward way to flash and debug the module, as well as easy access to all interfaces from the XM132 module via pin-headers.
