Ai-Thinker Ai-WB2-32S-Kit WiFi & BLE 5.0 Development Board

Description

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. Features Dual connectivity with IEEE 802.11 b/g/n Wi-Fi and BLE 5.0 Comprehensive Wi-Fi security: WPS, WEP, WPA, WPA2 Personal, WPA2 Enterprise, WPA3 Bluetooth Mesh support for networked devices Flexible operating modes: Station + BLE, Station + SoftAP + BLE 32-bit RISC CPU with 276KB RAM for efficient processing Secure boot with ECC-256 signature support Real-time AES decryption (OTFAD) for QSPI and SPI Flash (AES 128 CTR mode) Advanced encryption: AES 128, 192, and 256-bit engines Hashing support: SHA-1/224/256 True Random Number Generator (TRNG) Public Key Accelerator (PKA) for large-number operations Rich peripheral interfaces: SDIO, SPI, UART, I2C, VDC, IR remote, PWM, ADC, DAC, PIR, GPIO Integrated Wi-Fi MAC/BB/RF/PA/LNA and Bluetooth components Ultra-low power consumption: 12μA in deep sleep mode Quick-start with universal AT commands Supports secondary development on Windows and Linux platforms Specifications Parameter Value Model Ai-WB2-32S-Kit Package DIP-38 Size 55 x 25.4 mm Antenna On-board PCB antenna Frequency Range 2400 ~ 2483.5 MHz Operating Temperature -40°C ~ 85°C Storage Environment -40°C ~ 125°C, <90% RH Power Supply 3.3V or 5V, ≥500mA Interfaces UART, GPIO, ADC, PWM, I2C, SPI Serial Port Rate Default 115200 bps Security WPS, WEP, WPA, WPA2 Personal, WPA2 Enterprise, WPA3 Flash Default 4MB Wi-Fi RF Performance Spectrum Range 2400 ~ 2483.5 MHz Output Power (11n mode HT20) 16 dBm Output Power (11g mode) 17 dBm Output Power (11b mode) 19 dBm Receiving Sensitivity (11b, 1Mbps) -98 dBm Receiving Sensitivity (11b, 11Mbps) -90 dBm Receiving Sensitivity (11g, 6Mbps) -93 dBm Receiving Sensitivity (11g, 54Mbps) -76 dBm Receiving Sensitivity (11n, HT20, MCS7) -73 dBm BLE RF Performance Spectrum Range 2400 ~ 2483.5 MHz Output Power (1Mbps) 9 dBm (typical), up to 15 dBm Receiving Sensitivity (1Mbps @ 30.8% PER) -96 dBm Power Consumption Tx 802.11b, 11Mbps, POUT=+21dBm 260 mA Tx 802.11g, 54Mbps, POUT=+18dBm 245 mA Tx 802.11n, MCS7, POUT=+17dBm 230 mA Rx 802.11b/g/n, 1024 bytes 65 mA Deep Sleep 12 μA Applications Internet of Things (IoT) devices Mobile devices and accessories Wearable electronics Smart home automation systems Industrial automation solutions Certifications Ai-WB2-32S SRRC DataSheet Ai-WB2-32S-Kit
