WEILA WKV553 Supports Matter 1.2 Light Device Development

WEILA has confirmed that the WKV553 wireless module supports Matter 1.2 Light device development and the related product certification process.

Based on the GigaDevice GD32VW553 wireless platform, WKV553 integrates 2.4 GHz Wi-Fi 6, Bluetooth Low Energy 5.2 and a 32-bit RISC-V processor. A WKV553 development board is also available for hardware integration, wireless-function evaluation and project-level Matter development.

The module provides a practical wireless and processing platform for manufacturers developing Matter-enabled lighting products.

Based on a Matter 1.2 Light-Certified Platform

The GD32VW553 platform used by WKV553 has passed Matter 1.2 Light device certification, according to GigaDevice.

This provides a confirmed technical foundation for Matter lighting projects based on WKV553. Potential applications include:

   - Smart bulbs

   - Smart ceiling lights

   - LED lighting controllers

   - Connected lighting panels

   - Other Matter-enabled lighting products

It is important to distinguish the underlying platform certification from certification of the finished product.

The GD32VW553 platform certification does not automatically mean that every WKV553-based product is already Matter certified. Each finished lighting device must follow the applicable implementation, testing and certification procedures for its final hardware, firmware and device type.

Wi-Fi 6 for Matter over Wi-Fi Connectivity

Matter is an IP-based protocol that can operate over Wi-Fi and other supported network transports.

WKV553 supports 2.4 GHz IEEE 802.11 b/g/n/ax connectivity, allowing it to provide the Wi-Fi network connection for a Matter over Wi-Fi Light device.

Supported Wi-Fi features include:

   - IEEE 802.11 b/g/n/ax

   - WPA, WPA2 and WPA3

   - Target Wake Time

   - OFDMA-based random access

   - Multiple BSSID operation

   - Integrated TCP/IP protocol stack

   - A-MPDU transmission and reception

After commissioning, Wi-Fi can provide the IP network connection used by the Matter device. The final network behavior depends on the product firmware, lighting-control logic and complete system architecture.

No specific performance improvement percentage should be assumed without project-level testing.

BLE 5.2 for Device Commissioning

WKV553 also integrates Bluetooth Low Energy 5.2.

Matter commonly uses BLE during the commissioning process. BLE establishes a short-range connection that helps the device receive the information required to join the target network.

The module supports:

   - Bluetooth Low Energy 5.2

   - High-speed 2M PHY

   - Long-range coded PHY

   - Data rates of 250, 500, 1000 and 2000 kbps

By combining Wi-Fi 6 and BLE 5.2 in one module, WKV553 can reduce the need to integrate separate Wi-Fi and Bluetooth components.

The exact commissioning method must be defined according to the project firmware and application requirements. NFC commissioning is not included in this article because it has not been confirmed for the current WKV553 solution.

RISC-V Processing and Embedded Resources

WKV553 is based on the GigaDevice GD32VW553 chipset, which integrates a low-power 32-bit RISC-V processor operating at up to 160 MHz.

The module provides:

   - Up to 4 MB on-chip Flash memory

   - Up to 320 KB SRAM

   - One 12-bit ADC

   - SPI

   - QSPI

   - I²C

   - USART

   - UART

   - General-purpose timers

   - PWM timer

The chipset also integrates cryptographic acceleration, hash acceleration, public-key cryptography acceleration and a true random number generator.

WKV553 measures 18 × 20 mm, operates from a 1.8–3.6 V power supply and supports an operating temperature range of −40°C to +105°C.

Actual processor and memory availability must be evaluated according to the Matter implementation, lighting functions and application firmware used in the finished product.

WKV553 Development Board Available

A WKV553 development board is available for project evaluation.

Engineering teams can use the development board to evaluate:

   - WKV553 hardware integration

   - Wi-Fi 6 connectivity

   - BLE 5.2 communication

   - Host communication interfaces

   - Lighting-control architecture

   - Project-level Matter development requirements

The exact firmware, development tools and technical materials supplied should be defined according to the requirements of each project.

Manufacturers should provide their required Matter device type and lighting functions before requesting the development board.

What Manufacturers Should Confirm Before Development

Before beginning a Matter 1.2 Light device project, manufacturers should confirm:

   - Lighting product type

   - Required switching, dimming or color-control functions

   - Required Matter device type

   - Target Matter version

   - Host controller and communication interfaces

   - Power supply requirements

   - Antenna and enclosure conditions

   - Required commissioning workflow

   - Target application or ecosystem

   - Finished-product certification requirements

   - Prototype and production quantities

These details allow WEILA to evaluate the module, development board, firmware and PCBA requirements as one complete project.
