Wireless

Choosing a Wi-Fi module is a decision that affects the architecture, stability, and development of the entire device. It’s not just a matter of comparing specifications - it requires taking into account the operating environment and the nature of the application. In this article, we show you how to choose the right device by reviewing solutions ranging from the ESP32-C series, through the ESP32-S, to the ESP32-E22 with Wi-Fi 6E, based on real-world project requirements.

ESP32-S31 is Espressif’s new SoC, positioned as a more advanced evolution of the ESP32-S3 for next-generation IoT devices. With Wi-Fi 6, Bluetooth 5.4, expanded HMI and multimedia capabilities, and stronger security features, it opens the door to more demanding smart home, automation, audio, and edge AI applications. In this article, we look at the key features of ESP32-S31 and compare it with its predecessor.

Wi-Fi in industrial controllers is gaining importance because it significantly simplifies the installation, modernization, and remote operation of devices. It is used, among other things, in machine monitoring, IoT gateways, logistics, the energy sector, and HVAC systems. However, simply choosing wireless communication is just the beginning - it is crucial to tailor Wi-Fi parameters to operating conditions, application requirements, and design specifications.

The new ESP32-H21 chip from Espressif is designed for IoT device designers who need energy-efficient wireless communication and broad compatibility with modern network standards. With support for technologies such as Thread, ZigBee, Matter, and Bluetooth Low Energy, as well as optimized power management, the chip can be used in many smart home devices, monitoring systems, and building automation.

ESP32-E22 is Espressif's first chip to support the Wi-Fi 6E standard and, at the same time, an advanced communication coprocessor. Faster data transmission, more stable connections and new possibilities for the Internet of Things – this is how ESP32-E22 can be described in a nutshell. The new Espressif chip introduces technologies that can drive the next generation of smart devices.

The new generation of 5G connectivity eliminates the previous limitations of speed, latency and scalability. With Quectel modules, applications that previously remained in the realm of dreams become possible - from autonomous vehicles to smart factories.
