Ai-Thinker Ai-WB2-32S-Kit WiFi & BLE 5.0 Development Board
The Ai-Thinker Ai-WB2-32S-Kit is a powerful and versatile development board built around the Ai-WB2-32S module. Featuring the BL602 chip, this board supports both Wi-Fi (IEEE 802.11 b/g/n) and Bluetooth Low Energy (BLE) 5.0 protocols, making it an excellent choice for Internet of Things (IoT) projects, mobile devices, wearable electronics, and smart home applications. With a 32-bit RISC CPU, 276KB RAM, and an extensive set of peripheral interfaces—including SDIO, SPI, UART, I2C, PWM, ADC, DAC, and GPIO—this board offers robust performance and flexibility. The Ai-WB2-32S-Kit comes in a convenient DIP-38 package with an on-board PCB antenna, ensuring easy integration and reliable wireless connectivity. It supports advanced security features like WPA3 and low-power modes with a deep sleep current of just 12μA, making it ideal for both prototyping and production.
