Ai-WS1 Series Special Modules

1. Product Introduction

- Overview

Ai-WS1 Series

• Ai-WS1 is a Wi-Fi 6+BLE5.2+SLE1.0 module developed by Ai-Thinker Co., Ltd. The module is available in two models, Ai-WS1-CBS and Ai-WS1-CBE, equipped with core processors Hi3873S and Hi3873E respectively. Both are highly integrated 2.4GHz SoC chips supporting Wi-Fi 802.11b/g/n/ax, BLE5.2, and SLE1.0. The Hi3873S and Hi3873E feature high-performance self-developed 32-bit CPUs with a maximum clock speed of 240MHz.
• The Hi3873S chip integrates a high-performance 32-bit microprocessor and security processing engine, providing UART and GPIO interfaces, and supporting a high-speed SDIO2.0 interface with a maximum clock rate of 50MHz. As a slave device, it connects to the host MCU via the SDIO interface.
• The Hi3873E chip integrates a high-performance 32-bit microprocessor and security processing engine, providing UART and GPIO interfaces, and supporting a USB2.0 interface with a maximum speed of 480Mbps. As a slave device, it connects to the host MCU via the USB interface.
