Kit includes The HAT+ comes with 25mm standoffs (x4), booster header (x1) and screws (x8), so it can be used with a Raspberry Pi 5 with Active Cooler attached (Raspberry Pi and Active Cooler are sold separately). About DreamHAT+ Radar The 60 GHz mm-wave DreamHAT+ Radar is a cutting-edge Raspberry Pi 4B and 5 add-on, offering advanced ultra-wide band (UWB) frequency modulated continuous wave (FMCW) radar sensing capabilities in a compact and user-friendly package.The DreamHAT+ is built around the Infineon BGT60TR13C radar MMIC with 4 integrated antennas on the chip (1 transmitting antenna and 3 receiving antennas) to offer directional sensing and motion tracking in a wide range of applications, from robotics and smart home automation to proximity monitoring and gesture recognition. By leveraging millimetre-wave FMCW radar technology, the DreamHAT+ achieves exceptional precision even in challenging conditions such as low light, smoky, and foggy environments where cameras fail. Features High-Resolution Sensing: Achieve millimetre-level accuracy to detect objects, gestures, and movement. Perfect for dynamic environments requiring precise sensing. Plug & Play: Enjoy effortless integration within the Raspberry Pi ecosystem using the included open-source Python library. Also contains power and activity LEDs Real-Time Data Processing: Real-time data acquisition, processing, and visualisation in fast-changing conditions. Advanced Features: Leverage configurable sensing ranges up to 15 meters and various modes tailored for specific applications. Ready to Deploy: Accelerate your prototyping journey with provided sample code, examples, and comprehensive documentation. IoT ready: Low Power Consumption (~0.5W typical) makes it suitable for multicomponent operation and reduces thermal throttling. Standardised Architecture: Conforms to the Raspberry Pi HAT+ specification. Radar Specifications Operating Frequency 58 – 63.5 GHz Transmission Bandwidth 5 GHz Output Power
