WD – 219: The Intelligent Companion of Shared E-Bikes
The development of shared e-bikes has brought great convenience to our travel, and WD - 219 is the intelligent companion of shared e-bikes, providing strong IoT support.
WD - 219 has a sub-meter level positioning function that can accurately locate the vehicle position and solve the problem of positioning drift. It also supports inertial navigation algorithms, enhancing the positioning ability in areas with weak signals. At the same time, its ultra-low power consumption feature significantly extends the standby time.
In addition, this product supports dual-channel 485 communication, and the peripheral accessory expansion is stronger. It can support high-flow data return such as AI camera pictures without affecting the data interaction of the battery and the controller. It also supports industrial-grade surface mount technology with stronger anti-interference ability.
Choosing WD - 219 means choosing intelligence, convenience, and reliability, making the operation of shared e-bikes more efficient and the user experience better.
