Walabot60ghz Evaluation Kit Hardware spec Chapter 1 Introduction This guide provides information on the installation and operation of the Vayyar vTrig-CTPA0 Evaluation Kit. VTrig_CTPA0 is a three-dimensional mm-wave sensor used as a fixed field disturbance sensor or short-range device for interactive motion sensing. The device is installed on a wall or ceiling, and detects objects in a defined arena and displays a real-time image of their positions within the arena.
Walabot60ghz Evaluation Kit Hardware spec Chapter 2 System Overview The VTrig_CTPA0 system is designed to demonstrate Vayyar's 3D imaging non-contact RF sensors, which enable to identify multiple objects (“blobs”) in a defined space (“arena”). 2.1 System Architecture The VTrig_CTPA0 system architecture and connectivity scheme is illustrated in the figure below. Figure 1: VTrig_CTPA0 System Architecture The VTrig_CTPA0 system is comprised of the following components: The VTrig_CTPA0 RF Sensor Unit.
Walabot60ghz Evaluation Kit Hardware spec NOTE The Web GUI and API Client software can run either on their own dedicated PC, or on the same PC as the EVK Engine. 2.2 Hardware The figure below presents a high-level block diagram of the PCB that houses the EVK sensor unit: Figure 2: High-Level Block Diagram The following components are embedded in the sensor unit PCB: Vayyar VYYR7201-A0 system-on-chip (SoC). 40 embedded Tx/Rx linear polarized PCB embedded, wide-band antennas.

Walabot60ghz Evaluation Kit 2.2.2 Hardware spec Digital Interface The digital interface connects the host PC with the EVK board. The interface is implemented on the EVK board using an MCU and a micro-USB connector. Micro-Controller Unit (MCU) Cypress’s EZ-USB FX3™ MCU integrates the USB 2.0 physical layers (PHYs), and contains a 32-bit ARM926EJ-S microprocessor for building custom USB SuperSpeed applications.
Walabot60ghz Evaluation Kit 2.2.3 Hardware spec RF Interface - Antennas The array of 40 antennas serves to connect the sensor unit with the environment. The antennas are embedded in the PCB, as depicted in the figure below. Figure 4: Antenna Positions and Numbering For each transmitting (TX) antenna, there are multiple receiving (RX) antennas for collecting and recording the received RF signals. Each RX antenna and its associated TX antenna serve as an antenna pair. 2.2.
Walabot60ghz Evaluation Kit 2.2.5 Hardware spec Antenna and RF Characteristics The following are antenna and RF characteristics, based on the simulation of a single antenna over an infinite ground plane: Table 4: Antenna and RF Characteristics Parameter Value Comment Gain 5 dBi @62 GHz At 0˚ Elevation, 0˚ Azimuth Antenna -5dB beamwidth 160 deg. @62 GHz (E-plane) 120 deg.
Walabot60ghz Evaluation Kit 2.3 Hardware spec Software The VTrig_CTPA0 system software performs signal processing and generation of the arena image. The Graphical User Interface (GUI) provides images and blobs corresponding to the detected objects in the arena. NOTE The Graphical User Interface supports use of a single sensor only.
Walabot60ghz Evaluation Kit Hardware spec Chapter 3 Outputs Outputs from the sensor can be presented either through Web GUI or API. The data can be saved as MAT files and post-processed or analyzed in parallel to the saving. The output data is available as a raw data or as a 3D/2D image data. 3.1 Web GUI User-interface client software that communicates with the EVK Engine via a TCP/IP connection.
Walabot60ghz Evaluation Kit 3.2 Hardware spec API The Vayyar Application Programming Interface (API) provides programmatic access to the Vayyar EVK Engine, allowing for integration of Vayyar’s non-contact RF sensors into customer-developed systems. The outputs (raw data or the 3D/2D Image data) can be received by API in parallel or instead of the Web GUI.
Walabot60ghz Evaluation Kit Hardware spec Chapter 4 Regulatory section The device is certified under FCC part 15 section 15.255, as - FCC-ID : 2AHIS-V60G. This V60G device has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
