Tough

SKU:K034

Description

Tough is an industrial-grade programmable embedded controller. It is equipped with the Espressif ESP32 main control chip, which integrates Wi-Fi and features a dual-core low-power Xtensa® 32-bit LX6 microprocessor with a main frequency of up to 240MHz. The board includes 8M PSRAM + 16M FLASH memory, a 2.0-inch 320x240 full-color IPS display, a high-sensitivity capacitive touch panel, and a variety of peripheral and expansion interfaces. The fully enclosed casing offers dustproof and waterproof protection, ensuring stable circuit operation even in complex industrial environments. This controller is suitable for scenarios such as industrial field control, smart buildings, and outdoor data acquisition nodes.
