Hello everyone. This week, Let’s talk about Bluetooth and wifi modules products from our partner and supplier, Ai-Thinker. Their products provide additional options when selecting Bluetooth and wifi modules.
One of the smallest wifi modules packaged by Ai-Thinker is the Ai-WB2-M1 WiFi+BLE two-in-one series.

I am introducing the Ai-WB2-M1 and Ai-WB2-M1-I modules because they exemplify Ai-Thinker’s wifi modules and bluetooth modules in remarkably compact packaging. The Ai-WB2-M1 follows the classic Mini package series (ESP-C3-M1/ESP-C3-M1-1) but offers additional functionality while retaining full hardware compatibility.
In the following, LCSC electronics will introduce some advantages of Ai-Thinker’s WiFi+BLE two-in-one module Ai-WB2-M1.
Extremely Small Size, Classic Continuation
The smaller the module size, the higher the integration level. “Small” also means that wifi modules design require higher technical requirements. Small package modules can save product PCB space and bring more flexible solutions to product structural design and industrial design.
We can look at the dimensions of Ai-Thinker’s wifi modules and bluetooth modules ESP-C3-M1/ESP-C3-M1-1 and Ai-WB2-M1/Ai-WB2-M1-I. They are both 16.6*13.2*2.4mm/12.5*13.2* 2.4mm, fully compatible with hardware.

Let’s take a look at the pin definitions of Ai-WB2-M1 and ESP-C3-M1. They both have 61 pins.
Users who previously utilized ESP-C3-M1/ESP-C3-M1-1 can upgrade to Ai-WB2-M1/Ai-WB2-M1-I for seamless replacement.
WiFi+Bluetooth Two-in-one, Small but Excellent Ultimate Performance
The Ai-Thinker Ai-WB2-M1 module boasts high integration with a maximum of 61 pins. It retains the Mini series’ small form factor while offering improved performance.
The Ai-WB2 series, part of the “WiFi+X Big Connection” product line by Ai-Thinker, expands beyond traditional WiFi modules to include WiFi+BLE+X. Ai-WB2-M1 features a central BL602 chip as its processor, supporting the WiFi 802.11b/g/n protocol and the Bluetooth Low Energy (BLE) 5.0 protocol. Additionally, the BL602 chip includes a low-power 32-bit RISC CPU, 276KB of RAM, and a variety of peripheral interfaces such as SDIO, SPI, UART, I2C, IR remote, PWM, ADC, DAC, PIR, and GPIO. It has versatile applications in the Internet of Things (IoT), mobile devices, wearable electronics, smart homes, and other fields.
Meet Manufacturers’low-cost, Consumer-friendly Needs
As the intelligence capabilities of smart home appliances continue to improve, wireless communication (including wifi modules) solutions are becoming increasingly comprehensive. Cost control is the top priority for hardware manufacturers.
So, how can Ai-Thinker achieve low cost and low power consumption? Ai-WB2-M1 integrates WiFi modules and Bluetooth onto a single chip, meaning consumers only pay the price of one to get two services. Who wouldn’t want this? Integrated low-power 32-bit RISC CPU effectively reduces system power consumption and cost.
In terms of software algorithms, the Ai-Thinker Ai-WB2-M1 provides various sleep modes. For instance, when the device requires functioning in a low-power mode, the module adjusts autonomously to minimize energy consumption.
Product Stability and Reliability
Ai-Thinker prioritizes product stability and reliability. The Ai-WB2-M1 wifi modules and BLE passed a 43-day double 85 test before leaving the factory. What is the Double 85 Test? It is a reliability test where the module undergoes 1,000 hours of operation under conditions of 85°C temperature and 85% humidity.
The Ai-Thinker Ai-WB2 series wifi modules products that have passed the double 85 test have higher reliability and stability. They can effectively reduce the problems of equipment network disconnection, network delay and improve the product’s quality.
Ai-ThinkerAi-WB2 Series Wifi Modules Support Matter Protocol
Matter is a standardized smart home interconnection protocol that overcomes ecological barriers.
For product manufacturers, using products that support Matter will increase the competitiveness of their products. End users also benefit from Matter, as they no longer need to download multiple apps to control smart home appliances from different brands. One app can control all devices that support the Matter protocol.
Moreover, the Ai-Thinker Ai-WB2-M1 enables speedy use and supports general AT commands and SDK secondary development. It integrates with Windows and Linux development environments.
Whether you have experience with the Ai-Thinker Ai-WB2-M1 series, you can confidently utilize it.
