AI-WB2-M1-I

RF Transceiver Modules And Modems Overview

The Ai-WB2-M1-I is a compact Wi-Fi and Bluetooth Low Energy (BLE) module developed by Ai-Thinker, utilizing the BL602 chip as its core processor. It supports IEEE 802.11 b/g/n Wi-Fi protocols and BLE 5.0 standards. The module integrates a 32-bit RISC CPU with 276KB of RAM and provides extensive peripheral interfaces including SDIO, SPI, UART, I2C, PWM, ADC, DAC, and GPIO. Designed for space-constrained IoT applications, it features hardware compatibility with similar mini-form-factor modules.

• Wearable electronics with strict size limitations
• IoT sensors needing simultaneous Wi-Fi and BLE communication
• Mobile device accessories and peripherals

RF Transceiver Modules And Modems Procurement Notes

Verify that the specific suffix 'I' in the model number corresponds to the intended antenna configuration or regional certification requirements. Confirm physical dimensions match the target PCB footprint, particularly regarding the 12.5x13.2mm variant. Ensure the design accommodates the required peripheral interface connections as defined in the official pinout documentation before finalizing procurement.

RF Transceiver Modules And Modems Selection Notes

Select this module when a small form factor is critical but dual-mode Wi-Fi and BLE functionality is required. It serves as a direct upgrade path for designs previously using compatible ESP-C3 mini modules. Consider the BL602 chip's processing power and memory limits against application complexity. Verify that the integrated security features meet the project's data protection standards.

RF Transceiver Modules And Modems Part Context

The Ai-WB2 series represents Ai-Thinker's expansion into combined wireless connectivity solutions. The M1 variant specifically targets ultra-compact applications, maintaining the physical dimensions of established mini-modules while introducing the BL602 chipset. This allows developers to transition from single-function Wi-Fi modules to dual-mode solutions without redesigning the hardware layout.

RF Transceiver Modules And Modems Replacement Considerations

The Ai-WB2-M1-I is designed for hardware compatibility with ESP-C3-M1 and ESP-C3-M1-1 modules. Developers can perform a direct pin-to-pin replacement on existing PCBs. However, firmware must be updated to support the BL602 architecture and Ai-Thinker's specific AT command set rather than Espressif's ecosystem.
