특징

  • PCR Click is a compact add-on board that allows you to use a pulsed coherent radar (PCR) in your application. This board features the XM125, the Entry+ PCR module from Acconeer. The XM125 uses an Acconeer A121 pulsed coherent radar system based on a patented PCR technology with picosecond time resolution. The PCR Click provides access to the interfaces from the module so that it can easily be flashed and debugged. This Click board™ makes the perfect solution for developing high-precision people presence detection with the capability to recognize movement within configurable zones, motion detection, parking space occupancy detection, and level measurement in tanks or waste containers with configurable update frequency.

  • HOW DOES IT WORK?

    PCR Click is based on the XM125, the Entry+ PCR module from Acconeer. The A121 used in the module works on 60GHz and is optimized for ultra-low power consumption and high performance. It integrates baseband, RF front-end, and antenna. The A121 is unaffected by natural interference, such as dust, noise, color, and direct or indirect light. It can be used for distance and velocity measurements, object tracking, gesture control, monitoring, proximity, motion, and material detection. The radar can measure absolute and relative distance ranges in millimeters and up to 20m of distance.

    The module is delivered with a bootloader, allowing you to download the Acconeer Radar System Software (RSS) software and the SDK (Software Development Kit) for standalone usage, where customers can embed their application on top of RSS software. For this purpose, the XM125 is equipped with an STM32L 32-bit ARM Cortex-M4 MCU with an 80MHz clock speed. In addition, there are RST and DFU buttons that allow you to start the module in the embedded bootloader. The PCR Click uses a CP2102, a highly integrated USB-to-UART bridge from Silicon Labs, to allow you to connect it to the PC over the USB C connector. Besides evaluation and debugging, you can also flash the module's USB C and UART interface.

    There are several headers on PCR Click. There is an SWD connector that you can use to upgrade the STM32L firmware. The J1 connector provides the GPIO0 and GPIO1 pins that are configurable for different functions. For debugging purposes, you can use a J2 connector and UART interface of the module with an external UART adapter.

    PCR Click uses a standard 2-wire UART interface to communicate with the host MCU with commonly used UART RX and TX pins. In addition, there is an I2C interface too. The I2C address can be selected over the ADDR SEL jumper. Besides the RST button, you can reset the module over the RST pin with a LOW logic State. In addition to resetting, you can wake up the module over the WUP pin. If an event occurs, the module can interrupt the host MCU over the INT pin.

    This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.
