Description

The Ai-WB2-07S module integrates AI-Thinker’s BL602 chip, a cost-effective SoC combining a 32-bit RISC-V processor, Wi-Fi MAC/BB/RF/PA/LNA, and Bluetooth LE 5.0 radio into a single 17x16mm SMD package. It provides a complete RF subsystem with on-chip power amplifier and low-noise amplifier, simplifying PCB design for space-constrained IoT products.

Engineered for low-power operation, the module supports multiple sleep modes, enabling long-term deployment in battery-powered sensor nodes and remote monitors. Its comprehensive security suite includes secure boot with ECC-256, AES hardware encryption/decryption, SHA hashing, and a true random number generator (TRNG), meeting requirements for secure device provisioning and data transmission in commercial applications.

Key Features

  • BL602 RISC-V core processor with 276KB SRAM for application logic and network stack processing.
  • Full Wi-Fi 802.11b/g/n compliance with support for WPA3, WPA2 Enterprise, and WPS security protocols.
  • Bluetooth 5.0 Low Energy and Bluetooth Mesh support for short-range device networks and beaconing.
  • Hardware-accelerated cryptography (AES-128/192/256, SHA-1/224/256, TRNG, PKA) for secure connections.
  • Extensive GPIO and peripheral interfaces (UART, SPI, I2C, ADC, DAC, PWM, IR) for sensor and actuator integration.
  • Ultra-low deep sleep current (12μA) enables multi-year operation on coin-cell or small LiPo batteries.
  • On-the-fly QSPI/SPI Flash AES decryption and secure boot with signed firmware images.
  • Universal AT command firmware for rapid prototyping and integration with host MCUs.

Applications

  • Smart home automation sensors and controllers (lights, plugs, climate).
  • Wearable electronic devices and health monitoring gadgets.
  • Industrial IoT (IIoT) wireless sensor nodes for telemetry and monitoring.
  • Bluetooth Mesh networks for lighting control and asset tracking.
  • Battery-powered remote sensors with periodic Wi-Fi data uploads.

Frequently Asked Questions

What development environment and toolchain are recommended for the Ai-WB2-07S?

AI-Thinker provides a complete SDK based on the BL602 chip, compatible with Windows and Linux environments. You can develop using the official Bouffalo Lab Dev Cube IDE or the open-source BL602 IoT SDK. The toolchain includes GCC RISC-V cross-compiler, flash programming utilities, and AT command firmware. For prototyping, start with the pre-loaded AT command set via a USB-to-UART adapter at 115200 baud to configure Wi-Fi and BLE connections.

How do I connect an external antenna to the Ai-WB2-07S module?

The module features an IPEX (MHF) connector for an external antenna. You will need a compatible IPEX-to-SMA pigtail cable or a directly matched 2.4GHz antenna with an IPEX plug. Ensure the antenna has a 50-ohm impedance and covers the 2400-2483.5 MHz band. For optimal RF performance, keep the antenna trace short on your PCB and follow the reference design's RF layout guidelines to minimize signal loss and impedance mismatch.

What is the power supply requirement and how do I achieve low power consumption?

Supply the module with a stable 3.3V DC source within the 2.7V to 3.6V range, capable of delivering brief peaks up to 500mA during RF transmission. To minimize average current, utilize the module's sleep modes via AT commands or SDK APIs. In deep sleep (12μA), the RAM is retained, and the device can be woken via GPIO or timer. Configure the Wi-Fi and BLE radios to transmit intermittently and use the lowest practical transmit power to extend battery life in field deployments.
