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.
