Main features of RYWB116

RYWB116 has obtained the certification required for legal use in Japan (certification number: 020-250425). This module is Wi-Fi (IEEE 802.11 b/g/n) compliant and can be used safely in Japan as a dedicated Wi-Fi communication device.

Although this product is equipped with Bluetooth functionality as hardware, only Wi-Fi can be used in Japan, as the technical certification in Japan has been obtained for Wi-Fi only.

・Simple control using AT commands: UART is supported as the host interface for the communication module, enabling simple use of on-chip Socket communication, HTTP Client, and MQTT Client functions. On-chip encrypted communication functions are also supported, and currently TLS1.0 to 1.2 can be used.

The UART interface supports a baud rate of 9600 to 921600 bps.

SPI Client mode interface is also supported, enabling communication using Wiseconnect(R) SAPI.

Outstanding RF performance: -98.5 dBm extremely high reception sensitivity Wi-Fi reception sensitivity is -98.5 dBm (at 1 Mbps DSSS), which is among the highest in the industry. This high sensitivity enables stable communication even in weak signal environments, with a maximum communication distance of 200 m (up to 266 m depending on the environment).

The ultra-low power design is ideal for battery operation and features multiple power modes to dramatically extend the uptime of battery-powered IoT edge devices and wearable devices.

-Quiescent current: 3 nA

-Standby current (WLAN Standby): 51 μA (with DTIM=10 setting)

Compact and lightweight: The compact form factor with built-in antenna weighs only 0.8g. The module size is also compact, making it ideal for mounting in limited space.

Various operation modes: In addition to the normal client mode, the device supports an access point mode that supports up to 16 clients and enterprise security, allowing for flexible network construction.
