M5Stack Tough ESP32 IoT development kit with waterproof case

The M5Stack Tough is an industrial-grade programmable controller with a waterproof and dustproof enclosure made of UV-resistant plastic. The device is based on the ESP32-D0WDQ6-V3 chip with a dual-core Xtensa LX6 processor and a clock speed of up to 240 MHz. It features 16 MB Flash and 8 MB PSRAM for extensive applications. The 2.0-inch IPS display with 320×240 pixels offers a high-quality capacitive touchscreen for user interaction. Power management is handled by the AXP192 chip along with the BM8563 RTC for real-time clock and timed wake-up functions. For audio, an NS4168 16-bit I2S amplifier with a 1W speaker is integrated. The integrated 12V to 5V DC-DC converter circuit enables flexible power supply, also via the RS485 interface. The device supports Grove expansions via three ports (I2C, GPIO, UART) and offers a microSD card slot. Development is done via Arduino, UIFlow or ESP-IDF.
