AI-WB2-12F

RF Transceiver Modules And Modems Overview

The Ai-WB2-12F is a 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 protocols for Wi-Fi and BLE 5.0 standards. The module features a 32-bit RISC CPU with 276KB RAM and integrates MAC, baseband, RF, PA, LNA, and BT functions. Key specifications include a maximum data rate of 72.2 Mbps at 20MHz bandwidth, support for WPS/WEP/WPA/WPA2 Personal/WPA3 security, and Bluetooth Mesh capabilities. It offers multiple sleep modes with a deep sleep current of 12μA. The physical dimensions are 24.0 x 16.0 x 3.1 mm in an SMD-22 package with an onboard antenna.

RF Transceiver Modules And Modems Procurement Notes

Verify that the specific unit received matches the Ai-WB2-12F designation and SMD-22 package type. Confirm the presence of the onboard antenna and correct pinout configuration for the BL602-based design. Ensure compatibility with the required 2.7V to 3.6V power supply range and check for any specific firmware version requirements for your intended application protocol stack.

RF Transceiver Modules And Modems Selection Notes

Select this module when both Wi-Fi infrastructure connectivity and BLE local control are required simultaneously. It serves as a direct pin-compatible replacement for ESP-12F and ESP-C3-12F designs, facilitating hardware reuse. Choose this part over single-mode modules if dual-protocol operation is necessary for fallback connectivity or hybrid control schemes in constrained form factors.

RF Transceiver Modules And Modems Part Context

The Ai-WB2-12F belongs to the Ai-WB2 series, which centers on the BL602 processor. This series distinguishes itself from the Ai-M61/Ai-M62 lines by focusing on Wi-Fi 4 and BLE 5.0 rather than Wi-Fi 6 and BLE 5.3. It shares the same foundational architecture as other Ai-WB2 variants but is specifically defined by its SMD-22 footprint and onboard antenna configuration, differentiating it from external antenna versions.

RF Transceiver Modules And Modems Replacement Considerations

Public documentation confirms pin and form-factor compatibility with ESP-12F and ESP-C3-12F modules. Developers migrating from these platforms should verify software adaptation for the BL602 SDK and AT command set differences. No other direct substitute part numbers are explicitly listed in the provided official sources.
