Transmits UWB positioning data with 10cm accuracy over Wi-Fi REYAX Anchor Device with Technical Regulations Certification RYUW122_ANCHOR1" now available in Japan

M2M Craft Corporation (headquartered in Sapporo, Hokkaido, Japan) will begin importing and selling RYUW122_ANCHOR1, a UWB anchor device with Wi-Fi communication function manufactured by REYAX Technology, Taiwan, in Japan in February 2026. This product features wireless transmission of UWB ranging data with 10cm accuracy via Wi-Fi, and is a base station device with an integrated module that has acquired Japanese domestic technical conformity certification. It is intended for use in the construction of high-precision positioning systems in factories, warehouses, research facilities, etc.

In addition to UWB and Wi-Fi modules that have acquired technical certification, this kit provides software for positioning and development assets all in one package, significantly shortening the development time for UWB positioning systems.

Product Overview and Internal Configuration

RYUW122_ANCHOR1 is an integrated device that functions as a base station (anchor) for UWB positioning systems. This product integrates the following major components on a single board, with the STM32(R) MCU as the core of control.

RYUW122 UWB module: Provides precise positioning with 10cm accuracy.

RYWB116 Wi-Fi module: Transmits positioning data wirelessly via Wi-Fi.

USB to UART bridge: The module is equipped with a SILABS CP2102N-A02 and can be configured using AT commands via serial communication via USB TYPE-C.

Power supply and debugging: A USB TYPE-C connector for 5V DC supply and a pin header for ST-LINK/V2 for program writing and debugging are provided, allowing customized firmware to be written and used.

Anchor board firmware source code in C language for STM32L1 that relays commands received via USB to UART bridge to RYUW122 and RYWB116 devices and sends distance information of tags measured with UWB via WiFi. Firmware source code

C# source code for tag coordinate calculation application: Sample application source code that calculates tag coordinates based on the location of the anchor device by receiving tag ranging information from the anchor device on a PC.

Compliance with Japanese domestic laws and regulations (technical compliance information)

The wireless module installed in this product has already obtained the technical conformity certification in Japan.

The UWB module "RYUW122": Certificate No. 020-250092.

Wi-Fi module "RYWB116": Certification No. 020-250425.

RYWB116 is also compatible with Bluetooth 5.0, but only the Wi-Fi communication function can be used in Japan because it has not obtained the technical qualification for Bluetooth.

■"Superior basic specs" to support on-site operation

Both devices incorporate REYAX's state-of-the-art wireless technology.

The Wi-Fi module mounted on the anchor boasts an extremely high reception sensitivity of up to -98.5 dBm and can transmit data up to 200 meters. The UWB module also has a transmission range of up to 100 m in an unobstructed environment.

Low power consumption (Ultra Low Power): The "Ultra Low Power" design optimizes overall system energy efficiency.

Flexible control specifications with AT commands

Both RYUW122 and RYWB116 modules can be configured and controlled using AT commands via serial communication via USB connection, allowing users to change settings such as UWB network ID and PIN, access points used for Wi-Fi, and IP addresses and port numbers to which ranging data is sent. The UWB network ID and PIN can be changed.

■System Linkage and Software

The anchors are connected via Wi-Fi to a C# GUI application (TCP server) running on Windows(R). Distance data measured by each anchor is aggregated and coordinates are calculated and displayed in real time.

Sample AT commands used to configure the communication module are provided as a script file for the serial communication application Docklight(R).
