[Ai-WB2 Getting Started] Ai-WB2 Overview

1. Ai-WB2 Introduction The Ai-WB2 series modules are Wi-Fi & BLE modules developed by Shenzhen Ai-Thinker Technology Co., Ltd. They are powered by the BL602 chip as the core processor and support Wi-Fi 802.11b/g/n and BLE 5.0 protocols. The BL602 chip integrates a low-power 32-bit RISC CPU, 276KB RAM, and rich peripheral interfaces including SDIO, SPI, UART, I2C, IR remote, PWM, ADC, DAC, PIR and GPIO, among others. They can be widely used in the Internet of Things (IoT), mobile devices, wearable electronics, smart home and other fields.
