Built around an 802.11 single-chip transceiver with integrated RF power amplifier (PA) and a powerful STM32 32-bit microcontroller with extensive GPIO support, our Wi-Fi modules have on-board clocks generation and voltage regulators and can be chosen with either an integrated antenna (-A suffix) or u.Fl connector (-C suffix) for expanded RF coverage.
They come with a complete TCP/IP stack and a user-friendly application layer that ensures a simple and effective way to use the modules via AT commands. The latest models (available on STWF04S) also support the MicroPython compiler and runtime implementation of the Python 3 programming language optimized to run in resource-constrained environments. Our specific implementation, providing TFTP, HTTP, MQTT, SMTP, and WebSocket classes, makes it even easier to write highly optimized code.
Our Wi-Fi modules are FCC (US), CE (EU) and IC (Industry Canada) certified, thus providing a fast, flexible and affordable Plug & Play solution for adding of 802.11 b/g/n and TCP/IP connectivity to IoT designs.
With reduced power consumption and small form factor, the modules are ideal for both fixed and mobile wireless applications where a complete from-scratch Wi-Fi connectivity design is not an option due to technical (lack of specific RF engineering know-how at hand), time-to-market (avoids lengthy certification processes) or total-cost-of-ownership (it helps drastically cut development costs) considerations.
To further ease development with our Wi-Fi modules, dedicated X-Nucleo expansion boards and expansion software libraries, with implementation examples, are available to give access to all the capabilities of our STM32 Open Development Environment.
All our modules are RoHS compliant.
