Description

Ai-WB2-32S-Kit is a development board designed for the Ai-WB2-32S module. The module is equipped with a BL602 chip as the core processor and support Wi-Fi 802.11b/g/n protocol and BLE5.0 protocol. The BL602 chip has a built-in low-power 32-bit RISC CPU, 276KB RAM, and rich peripheral interfaces, including SDIO, SPI, UART, I2C, IR remote, PWM, ADC, DAC, PIR, GPIO, etc. Support three power supply methods: Type-C (recommended), 5V+GND, 3V3+GND, and supply current ≥ 500mA. It can be widely used in the Internet of Things, mobile devices, wearable electronic devices, smart homes, and other fields.
