UWB AOA Module
This product consists of an anchor and a tag. The anchor can output the distance and angle of the tag relative to the anchor through serial port in real time. The ranging range is 30 meters, and the angle measuring range is 360 degrees, which is symmetrical before and after. The distance accuracy is 250px and the angle accuracy is 5 degrees. This module is suitable for all kinds of automatic following products.
Angle Description
The front of the anchor is 0 degrees, the left side is 0 to -90 degrees, and the right side is 0 to +90 degrees, and it is symmetrical before and after. The following module itself cannot distinguish between front and back, but when the tag is on the back of the anchor, the trolley will touch positive feedback when turning, and accelerate to the front.
Communication Protocol
Serial port TTL3.3V baud rate is 115200, and the calibration does not include the header
