M5Stack Tough ESP32 IoT Development Board Kit

The M5Stack TOUGH Waterproof** ESP32 embedded controller is an industrial-grade programmable embedded controller featuring an Espressif ESP32 chipset with integrated WiFi & Bluetooth dual-mode.

It is equipped with dual-core low power Xtensa® 32-bit LX6 microprocessor with a clock frequency of up to 240MHz. It’s a solid combination of 8M PSRAM + 16M FLASH memory, integrated 2′ HD IPS display panel + high-sensitive capacitive touch screen + rich peripherals and expansion interface.

The M5Stack TOUGH has full-coverage support making it dustproof and waterproof**, which can ensure the stability of circuit operation even in complex industrial applications.

The M5 TOUGH is ideal for industrial control, smart buildings, outdoor node data acquisition and other applications.

**Caution: Please DO NOT immerse the enclosure in water. There is no protection from immersion.
