Jiyi Back Obstacle Avoidance Radar Module - 24GHz FMCW, 1-25m Range, IP67

While the exact voltage is not specified in the provided data, typical 24GHz radar modules for drones operate on a 5V DC supply with a digital communication interface such as UART (Serial) or CAN bus for outputting distance data. You should consult the official Jiyi product datasheet for the precise pinout, voltage requirements (likely 3.3V or 5V logic), and protocol details for integration with your flight controller.

The IP67 rating indicates the module is completely dust-tight (6) and can withstand temporary immersion in water up to 1 meter deep for 30 minutes (7). This is critical for agricultural drones that operate in dusty fields, may encounter rain, or need to be washed down, ensuring the sensor's electronics are protected from environmental contaminants and moisture ingress.

Yes, the product description highlights its high sensitivity and optimized receiver gain for detecting fine obstacles such as electric wires, small tree trunks (~10 cm), and thin poles. The FMCW technology and dual-receive path architecture enhance its ability to resolve these challenging targets within its 1-25 meter operational range.

The module features fast signal transmission, which is essential for real-time obstacle avoidance. While a specific Hz value isn't listed, FMCW radar modules of this class typically offer update rates ranging from 10 Hz to 100 Hz, providing sufficiently frequent distance measurements for high-speed drone navigation and reactive avoidance maneuvers.
