A reversing radar typically consists of several key components, including a main control chip, reversing radar sensor, an ultrasonic transmitting and receiving circuit, an alarm circuit, and a display circuit. With ultrasonic distance measurement and features of high-performance, low power consumption, the latest reversing radar solution based on the APM32A407 series of automotive-grade MCUs enables rich, powerful, and convenient reverse radar recording functions.

APM32A407 Reversing Radar Advantages

•  Support radar signal collection and processing, enabling it to accurately detect and locate obstacles near the vehicle body.

•  Communicate to the reversing radar host via a CAN bus, which collects multi-channel radar data from multiple sensors.

•  Radar data can be saved in the external Flash through SPI.

•  Control commands can be sent via USART to the reversing radar system for configuration and calibration.

•  Realize USB HOST through USB OTG, read and write Flash data from external USB storage devices.

The high-performance APM32A407 series of MCUs stands out with its rich on-chip resources, peripherals, and low power consumption features. With these MCUs, the reversing radar system can achieve more functions with simple peripheral circuitry, reducing costs and enhancing the overall reliability of the system. Furthermore, the SWD/JTAG debug mode allows for convenient on-chip flash memory programming and software upgrades.
