TOUGH, the Waterproof ESP32 embedded controller, is an industrial-grade programmable embedded controller designed for demanding applications. Powered by the Espressif ESP32 chipset with integrated Wi-Fi, the esp32 kits feature a dual-core low-power Xtensa® 32-bit LX6 microprocessor with a clock frequency of up to 240MHz.

With a combination of 8M PSRAM and 16M FLASH memory, TOUGH offers ample storage capacity for your projects. It is equipped with a 2.0-inch HD IPS display panel, a high-sensitive capacitive touch screen, and a wide range of peripherals and expansion interfaces, providing versatility and flexibility for various applications.

TOUGH is built with full-coverage support, making it dustproof and waterproof. This rugged design ensures the stability of circuit operation, even in complex industrial environments. It is an ideal choice for industrial control systems, smart buildings, outdoor node data acquisition, and other challenging applications.

    Perfect for what I intended it for

    I needed some digital indicators on my boat, which should be flexible and sort of waterproof. These devices provide this functionality perfectly, although the color isn’t the prettiest. I’ll definitely order more in the future!

    M5Stack Tough ESP32 IoT Development Board Kit

    Delivery was flawless as usual. Works as expected. A bit disappointed the usual 3 buttons (A, B and C) have been eliminated (compared to M5Core2) but I guess that's due to the different touch hardware.
