WKV553 module is a dual-mode Wi-Fi 6 + Bluetooth 5.2 (BLE) wireless module developed by Guangdong WEILA Intelligent Technology Co., Ltd. The module is based on the GigaDevice GD32VW553 chipset, which integrates a low-power 32-bit RISC-V processor with a clock frequency of up to 160 MHz. It provides a rich set of peripherals, including ADC, SPI, QSPI, I²C, USART, UART, and more.

In addition to its powerful MCU capabilities, the GD32VW553 integrates 2.4 GHz Wi-Fi 6 and Bluetooth 5.2 Low Energy (LE) connectivity. Compared with traditional Wi-Fi 4, Wi-Fi 6 offers significant advantages such as higher bandwidth, greater network capacity, lower latency, and reduced power consumption, helping to optimize and enhance the performance of IoT devices.

Combined with BLE 5.2, the module can easily support Bluetooth provisioning (Bluetooth-assisted network configuration). Bluetooth can also operate independently for applications such as data transmission, device communication, and other wireless functions.

The WKV553 module is suitable for a wide range of applications, particularly in:

·  Smart Home Appliances

·  Smart Home Systems

·  Industrial IoT

·  Consumer Electronics

·  Portable and Handheld Devices

·  Electric Bicycles (E-bikes)

·  IoT Devices

·  Communication Gateways

·  Various Wireless Connectivity Applications
