The interface is incorrect. Just one correct one will do. Full specification coverage + highly compatible chips. Old devices, new digital products, engineering scenarios - goodbye to the troubles of "unable to plug in, unable to connect, unable to identify". Molded outer casing + thickened wire body, repeated plugging and unplugging for thousands of times still maintains stable contact. It is not easy to break even if frequently moved in the engineering site. Dual-layer shielding layer isolates strong electrical signal interference. In meeting rooms and exhibition halls, long-term operation will not have problems such as disconnection or interruption of identification. In large conference sites, it is most afraid of not being able to find the compatible adapter temporarily. The Explorer series is fully stocked in stock, and urgent orders can be dispatched on the same day, helping you minimize the risk of on-site debugging.
