Tuya Smart’s SS3L module is a low-power embedded Sub-GHz communication module with built-in network protocol stack and rich library functions. It supports developers to quickly access Tuya Smart’s IoT PaaS platform and use Tuya Smart’s Sub- The GHz Software Development Kit (SDK) makes it easy to develop embedded Sub-GHz communication products.

“By combining Tuya Smart’s SS3L module, Sub-GHz bi-directional protocol stack with mesh networking capabilities, and Sub-GHz SDK, we can help developers speed up the development process and shorten time to market.” Tuya Smart Asia Pacific Region General Manager Ross Luo said. “We are excited to use Silicon Labs’ wireless technology in our solutions, and they are an ideal partner to provide world-class wireless hardware and software, development tools and engineering support, enabling us to deliver industry-leading capabilities in global markets products and solutions.”

Silicon Labs’ EFR32FG SoC integrates an energy-efficient microcontroller (MCU) and a highly integrated wireless transceiver supporting Sub-GHz proprietary wireless protocols into Tuya Smart’s SS3L module. The SoC features 20dBm output power and low receive sensitivity for long-distance communication, while its 1.3µA deep-sleep mode power provides excellent energy efficiency. In addition, the device has AES-256/128 hardware encryption accelerator with ECC, SHA-1, SHA-2 algorithms, which can provide high security for IoT products.

“Sub-GHz wireless protocols are widely used in home, commercial and industrial IoT applications to provide high performance and high power efficiency,” said Matt Johnson, president of Silicon Labs. “We are delighted to work with Tuya Smart to implement their Sub-GHz solution with their own EFR32 Wireless Gecko SoC, thereby facilitating the development of low-power, long-range IoT devices for developers and customers. We look forward to We will continue to expand our partnership with Tuya Smart in the future.”

Tuya Smart and Silicon Labs have been working together to create various IoT solutions using various wireless technologies including Zigbee and Wi-Fi. Tuya Smart recently participated in the Asia Pacific conference of the 2021 Works With Developer Conference held by Silicon Labs. At the conference, Luo Zhijun, General Manager of Tuya Smart Asia Pacific Region, had a keynote conversation with Matt Johnson, President of Silicon Labs.
