This product is a microcontroller development board that supports 2.4GHz Wi-Fi and BLE 5. It integrates large-capacity Flash and PSRAM, and features an onboard 5-inch LCD screen, allowing for smooth operation of GUI programs such as LVGL. Combined with a variety of peripheral interfaces, it enables rapid development of ESP32-S3 HMI and other applications. Equipped with high-performance Xtensa 32-bit LX7 dual-core processor, with a main frequency of up to 240 MHz. Supports 2.4 GHz Wi-Fi (802.11 b/g) and Bluetooth 5(LE), with onboard antenna. Built-in 512KB and 384KB ROM, stacked with 16MB Flash and 8MB PSRAM. Onboard 5-inch LCD screen 1024x600 resolution, 65K color. Support interface to control capacitive touch, 5-point touch, support interrupt (touch version only). Onboard voltage regulator chip, supports 7V-36V wide voltage power supply. Onboard RTC chip and battery holder, after installing the battery, the time is not lost when the power is off. Onboard CAN, RS485, interface, Micro-SD card holder, MX1.25 2P battery interface and digital isolation type 10 and other resources. Input with bidirectional optocoupler isolation, supports passive and active switch input, active supports positive voltage and negative voltage. Output with optocoupler isolation, stronger driving capability, sink current up to 450mA (MAX). Supports flexible clock, module power individual setting and other precise control to achieve multi-scenario low power consumption mode.
