Ai-Thinker Rd-60 60GHz Human Motion Radar Module The Ai-Thinker Rd-60 is a low-power 60GHz FMCW millimeter-wave radar module designed for human motion, presence, tracking, and micro-motion sensing. It integrates a 60GHz AiP radar system, 1T3R antenna array, 2.4GHz wireless transceiver antenna, crystal, and Flash in a compact SMD24 module package. Compared with basic proximity or infrared sensing, Rd-60 provides a higher-frequency radar platform with wide field-of-view coverage, short-range response down to 0.01m, and a listed maximum sensing distance of up to 8m depending on target size and reflection characteristics. It also supports low-power operating modes and wireless protocol capabilities including BLE 5.3, 802.15.4, Thread, and Matter support according to the official specification.

VDDIO Limit — VDDIO is rated up to 3.6V, so level matching is required when the host IO voltage is not compatible. UART Planning — The specification lists serial port 0 for radar command reception and serial port 1 for radar data output. Antenna Clearance — Keep the antenna side facing the target area and avoid metal structures or high-frequency devices near the antenna. Stable Mounting — Fix the module firmly because vibration or movement of the radar module can affect detection results. Backside Shielding — If moving objects behind the radar cause unwanted detection, use suitable metal shielding or a backplane to reduce backlobe influence. Multi-Radar Layout — Avoid direct beam alignment between multiple 60GHz radar modules and keep them separated where possible. ESD Protection — Add ESD protection on power and external IO lines when the module is connected to exposed terminals or external wiring. Reflow Handling — Follow MSL level 3 storage and baking requirements before reflow soldering after the moisture-proof packaging is opened.
