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.

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.

Introducing the ESP32-P4, a new SoC from Espressif for advanced IoT applications. It includes a dual-core RISC-V processor, HMI support, advanced security and image processing features, and starts at $2. An ideal solution for modern IoT projects.

ESP-NOW is a low-power wireless protocol developed by Espressif for high-speed communication between IoT devices without the need for a router. It supports ESP8266 and ESP32 chips and provides low latency and secure long-distance transmission, making it ideal for smart home and industrial systems.
