Description

The Ai-WB2-13 module from AI-Thinker is a highly integrated wireless communication solution centered on the BL602 system-on-chip. This SoC combines a 32-bit RISC-V processor, Wi-Fi MAC/BB/RF front-end, and Bluetooth LE 5.0 radio into a single compact package. The on-board PCB antenna simplifies design-in, while the extensive GPIO and peripheral suite (including SPI, I2C, UART, ADC, and PWM) allows direct interfacing with sensors, displays, and control systems.

Engineered for low-power IoT applications, the module supports several sleep modes, achieving a deep sleep current of just 12μA to maximize operational lifespan on battery power. Its integrated hardware security accelerators ensure secure communication and device authentication. The module is supported by a universal AT command set for rapid prototyping and a full SDK for custom firmware development in Windows or Linux environments, making it suitable for smart home devices, wearable electronics, and industrial telemetry nodes.

Key Features

  • Compact SMD-18 Footprint: Measures only 20.0 x 18.0 x 3.1mm with an integrated PCB antenna for space-constrained designs.
  • Comprehensive Wireless Security: Supports WPS, WEP, WPA, WPA2 Personal/Enterprise, and WPA3 for secure network authentication.
  • Hardware Crypto Acceleration: Features dedicated engines for AES-128/192/256, SHA-1/224/256, True Random Number Generation (TRNG), and Public Key Accelerator (PKA).
  • Flexible Development Paths: Can be used with pre-programmed AT commands for quick integration or fully customized via the BL602 SDK with C/C++ toolchains.
  • Robust Thermal Design: Operates reliably across an industrial temperature range of -40°C to 85°C.
  • On-the-Fly Decryption: Supports OTFAD (On The Fly AES Decryption) for secure execution of encrypted firmware from external QSPI/SPI flash.

Applications

  • Smart Home Automation: Used in Wi-Fi smart plugs, lighting controls, and environment sensors connected to platforms like Home Assistant or Tuya.
  • Wearable & Portable Electronics: Enables data logging and wireless sync for health monitors, fitness trackers, and personal IoT gadgets.
  • Industrial IoT (IIoT) Telemetry: Connects sensor nodes for temperature, humidity, or vibration monitoring to cloud dashboards via Wi-Fi or BLE gateways.
  • Consumer Electronics: Integrates into toys, remote controls, and audio accessories requiring low-power, dual-mode wireless connectivity.

Frequently Asked Questions

What development environments are supported for programming the Ai-WB2-13 module?

The module is supported by the official BL602 SDK, which provides toolchains for Windows and Linux. You can develop in C/C++ using command-line tools or IDEs like VSCode. For quick start, use the universal AT command firmware via a UART connection at 115200 baud to configure Wi-Fi and BLE settings without custom coding.

How do I connect and power the Ai-WB2-13 module for initial testing?

Provide a stable 3.3V DC supply to the VCC and GND pins, ensuring your power source can deliver bursts up to 500mA. Connect a USB-to-UART adapter's TX/RX lines to the module's UART0_RX and UART0_TX pins. Use a serial terminal at 115200 baud to send AT commands like "AT+WJAP" to join a Wi-Fi network. An external 3.3V regulator is recommended for stable operation.

What is the procedure for updating or flashing new firmware onto the Ai-WB2-13?

Firmware flashing requires entering the bootloader mode by holding the GPIO8 pin low during power-up. Use the `bflb_mcu_tool` from the Bouffalo Lab SDK to connect via UART and upload your compiled .bin file. Ensure you have the correct partition table and bootloader. The process erases the existing firmware, so backup any configurations first.

Can I use an external antenna with the Ai-WB2-13 module instead of the PCB antenna?

The standard Ai-WB2-13 variant uses a fixed PCB antenna. For an external antenna, you would need a module variant with an IPEX connector or must carefully solder a coaxial cable to the RF pad, which requires impedance matching (50Ω) and RF layout expertise to avoid signal degradation. For most applications, the integrated antenna provides adequate range.

What are the key power consumption figures for designing a battery-powered node?

In active Wi-Fi transmission, current can peak above 200mA. During connected idle with Wi-Fi in sleep, expect currents around 10-20mA. The module achieves its lowest consumption in deep sleep mode, drawing approximately 12μA, which allows for years of operation on a coin cell when waking periodically. Use the provided PWM or GPIO to control peripheral power for further savings.
