Note: WLT reserves the right to select components from different suppliers to realize the functions of the module. At the same time, ensure that all mechanical and electrical specifications and module certifications are maintained. The design should be carried out within the scope of the physical dimensions of the machinery as shown in Figure 4-2. All measurements are in millimeters (mm).

Precautions
The module uses an external antenna, which is far away from metal devices as far as possible. Module reading distance is closely related to antenna size and card size, please adjust accordingly according to actual needs; Try to avoid touching the electronic components on the module without protective measures to reduce the possibility of electrostatic damage to the module.
