Description

The AI-Thinker Ai-WB2-01M is a highly integrated, DIP-18 packaged wireless module built around the BL602 system-on-chip. It combines a 32-bit RISC processor, RF front-end, power amplifier, and low-noise amplifier into a single 18x18mm footprint, providing a complete 2.4GHz Wi-Fi and Bluetooth Low Energy 5.0 solution for embedded designs.

Engineered for power-sensitive applications, the module supports multiple sleep modes, enabling efficient battery-powered deployments in smart home sensors, wearable devices, and industrial telemetry nodes. Its rich set of digital and analog interfaces, including SPI, I2C, UART, ADC, and PWM, allows for direct sensor integration and control without external microcontrollers.

Key Features

Dual-mode wireless connectivity supporting IEEE 802.11 b/g/n Wi-Fi and Bluetooth 5.0 with Mesh networking capability.
High-performance 32-bit RISC CPU core paired with 276KB of integrated SRAM for application logic and network stacks.
Advanced hardware security subsystem featuring AES-128/192/256 encryption, SHA-1/224/256 hashing, True Random Number Generator (TRNG), and Public Key Accelerator (PKA).
Flexible network roles: operates as Wi-Fi Station, Soft Access Point (AP), or concurrently as Station + SoftAP + BLE.
Low-power architecture with configurable sleep modes; deep sleep current is just 12 microamperes (µA).
On-board PCB antenna eliminates the need for external antenna components, simplifying PCB layout and BOM.
Comprehensive development support via universal AT command set and integrated SDKs for Windows and Linux environments.

Applications

Smart home automation devices (sensors, switches, lighting controls).
Wearable electronics and personal health monitoring gadgets.
Industrial IoT (IIoT) for wireless sensor networks and telemetry.
Battery-powered environmental monitors and data loggers.
Prototyping and product development for connected consumer electronics.

Frequently Asked Questions

What development environments are supported for programming the Ai-WB2-01M?

The module is supported by the official BL602 SDK, which provides toolchains for Windows and Linux. You can develop applications in C using the provided HAL and network APIs. It also supports a universal AT command firmware for quick serial-based control, allowing configuration and basic operations without direct SDK programming.

How do I connect to the module's UART interface for AT commands?

The module's default UART baud rate is 115200 bps. Connect the designated TX and RX pins (refer to the pinout diagram) to a USB-to-serial adapter. Power the module with 3.3V. You can then use a terminal program to send standard AT commands like "AT\r\n" to verify communication and configure Wi-Fi SSID, password, or BLE parameters.

What is the power consumption profile, and how do I enable deep sleep?

The module draws a peak current ≥500mA during active RF transmission. In deep sleep mode, consumption drops to approximately 12µA. To enter deep sleep, your application firmware must configure the appropriate power management registers via the SDK's PM API, disable peripherals, and then call the sleep function. GPIOs can be used as wake-up sources.

Can I use an external antenna with the Ai-WB2-01M module?

The standard Ai-WB2-01M variant comes with a fixed, on-board PCB antenna and does not have an external antenna connector like IPEX. For designs requiring an external antenna, you would need to select a different module variant from AI-Thinker's WB2 series that includes an IPEX connector or manually modify the RF layout, which requires careful impedance matching.
