With high-frequency contactless technology operating at 30 to 300 GHz, often known as mmWave is widely implemented as a sensing technology for proximity detection of objects and motion sensing. Since it operates at a high frequency, meaning the technology uses smaller wavelengths that help in giving it high accuracy and is capable of penetrating materials. Due to the increasing demand for industrial and automotive applications, D3 Engineering has announced its DesignCore RS-6843AOPUA mmWave Radar Sensor measuring 1-inch cube form factor. This small form factor sensor with a USB-Serial interface is designed for field testing, sensing evaluation, and algorithm development.

The tiny mmWave radar sensor is based around the ARM Cortex-R4F clocked with up to 200 MHz and Antenna-on-Package AWR6843AOP from the Texas Instrument. The AWR6843AOP single-chip radar device is an AECQ-100 qualified single-chip 60 GHz automotive radar sensor integrated with a DSP and MCU. It also features a radar accelerator and an antenna array in the package.

The processing cores in the AWR6843AOP include a C674x DSP for FMCW signal processing, a hardware accelerator for radar data processing, and a Cortex-R4F microcontroller for object tracking, classification, and communications.

The sensor has two variants, the RS-6843AOPA, and RS6843AOPUA. The former provides an additional option to connect it to baseboards via headers to get more interfaces and functionalities. While RS-6843AOPUA comes with a USB-C connector, which can be used to power the board or enumerate two serial UARTs (one for console and the other for algorithm outputs).
