XB112 /XM112 Pulsed Co-Herent Radar
The pulsed coherent radar module XM112 from Acconeer is a 24 mm x 16 mm module that integrates the A111 pulsed coherent radar and a 32-bit ARM® Cortex®-M7 ATSAME70Q20A microprocessor on the same printed circuit board (PCB). The ATSAME70Q20A is equipped with 384 Kbytes SRAM and 1 MB Flash and has a maximum core processor frequency of 300 MHz.
The XM112 is a reference module that can be integrated into a product via the slim 30-pin board-to-board connector to decrease users cost and time for bringing a product to market. The XM112 can also be used as an evaluation kit together with the breakout board XB112.
The XB112 is powered via a standard 5 V USB cable and contains a 1.8 V power supply as well as a USB-UART converter, so that the XM112 can be controlled from an external host computer via the USB port.
The XM112 is delivered with Acconeer RSS software including SDK (Software Development Kit) for stand-alone usage where customer can embed their own application on top of Acconeer RSS software. Acconeer RSS software provides API to set A111 sensor configuration and to retrieve supported radar services and detector data.
The XM112 module can also be controlled by external host using register based protocol (UART, SPI and I2C).
The module is suitable for applications in various market segments such as:
- IoT
- Automotive
- Industrial
- Robotics
- Drones
- Smart Cities
- Healthcare
- Mobile/Wearables
