U3 is an upgraded version of U2: CPU upgrades to M4, adds high-speed spectrum ysis and 5P male/female sockets, with richer protocols, and U3 detection does not need to plug in HID power supply The U3 standard version uses a plastic shell, which may have scratches, burrs, and ons with burrs, etc., which is not perfect, and perfect users are required to take careful shots. Remarks: The components, chs, interfaces, appearance, color deviation, pack and other materials of the product are different due to different batches of suppliers, and there are certain differences in performance. In the case of little change in performance, the actual product received by the user shall prevail. Further notice Please download , and manual from Weijian official website: www.witrn.com
