  "textContent": "The ESP32-E22 tri-band Wi-Fi 6E and Bluetooth 5.4 module has received a Wi-Fi CERTIFIED certificate from the Wi-Fi Alliance, and Espressif has also released WiFi and Bluetooth Linux drivers for the chip. The ESP32-E22 was first unveiled at CES 2026 with a dual-core RISC-V processor clocked at up to 500 MHz, 1MB RAM, tri-band WiFi 6E tested up to 2.1 Gbps with iperf, and dual-mode Bluetooth 5.4/6.0. While it also features 41 GPIO pins, it’s not mainly designed for IoT projects, but instead targets host-based wireless systems needing WiFi 6E / Bluetooth 5.4 connectivity through PCIe 2.0 or SDIO interfaces. In other words, the ESP32-E22 will likely show on M.2 modules, competing against similar products from MediaTek and Intel. Espressif has not said which module was tested for the Wi-Fi CERTIFIED certificate, but I suspect it should be the upcoming ESP32-E22-M2-1 M.2 module listed on the company’s website. From the certificate, [...]\n\nThe post Espressif ESP32-E22 WiFi 6E module gets Wi-Fi CERTIFIED certificate, an open-source WiFi and Bluetooth Linux drivers appeared first on CNX Software - Embedded Systems News.",
