TOUGH
Description
TOUGH is the embedded master control for industrial scenarios in the M5Stack development kit series. The main control ESP32 model is D0WDQ6-V3, with two Xtensa® 32-bit LX6 processors that can be controlled separately, the main frequency is up to 240Mhz, supports WiFi and Bluetooth functions, onboard 16MB Flash and 8MB PSRAM, and can be through TYPE-C interface Download programs and powerful configuration to meet the resource overhead of complex applications. The front is equipped with a 2.0-inch resistive touch screen. The built-in RTC module can provide accurate timing function. The power supply part is equipped with AXP192 power management chip. At the same time, the fuselage is equipped with a TF-card (microSD) card slot and speakers, and a power amplifier chip with I2S digital audio interface can effectively prevent audio signal distortion.
