Overview

The WLT5283M is a Bluetooth Low Power transparent transmission module from Wi- linktech. The module is mainly used in the Internet of Things data communication, through a wealth of peripheral interfaces to achieve data collection and control. In transparent transmission mode, the user’s product can quickly dock with the module and communicate with the mobile device to realize the intelligent control and management of the product.

WLT5283M is based on the Bluetooth Low Power 5.0 protocol, which can be used for transparent and encrypted point-to-point data transmission, and users do not need to care about the transmission protocol, only need to make simple Settings to communicate.

The module supports BLE (Up to Bluetooth 5.0) and BLE Mesh. Built-in 512kB FLASH supports dynamic stack and protocol Profile configuration, and product features can be configured via software, providing ultimate flexibility. Hardware OTA upgrades are also supported, allowing convenient product features to be rolled out and upgraded.

Note: Verentone reserves the right to select components from different suppliers to realize the functions of the module. At the same time, all mechanical and electrical specifications and module recognition are guaranteed Certificates are maintained. The design should be carried out within the physical dimensions of the machine as shown in Figure 5-2. All measurements are in millimeters (mm).

Precautions

Bluetooth works at 2.4GHz frequency, should try to avoid various factors on the wireless transceiver impact, pay attention to the following points:

• Avoid metal for the part of the product housing that encloses the module, and if the housing is metal, consider using an external antenna.
• Metal screws, etc. inside the product should be kept away from the RF portion of the module.
• In order to maximize RF performance, the user motherboard layout should follow the following recommendations:
• Antenna clearance area: The user motherboard located directly below the antenna area of the module must not have any copper foil wiring (including power, ground, signal layers). Module location: The module should ideally be arranged in a corner of the user’s motherboard, with the PCB antenna located at the far end of the motherboard. This position minimizes the headroom area of the antenna.

Refer to the PCB package
