GPS Module
Overview
This GPS module is based on the JRC G591 or ublox solution and is intended for reference design and testing with JiuDing boards such as the x210, i210, x4412, and x4418.
According to the provided material, the JRC G591 is designed by JRC of Japan and offers high-sensitivity satellite positioning. It maintains good positioning speed and accuracy in environments such as wide valleys and dense urban areas, and is compatible with common solutions such as Samsung 14B0102, HuanQiu ET312, ZaiTian RB310, and ublox 4X/5X.
