ESP32 development board with WiFi, Bluetooth, and a 2.8-inch screen.

Introduction：

ESP32 = MCU + WiFi + Bluetooth.
The ESP32 development board is based on the ESP32-DOWDQ6 controller, featuring a dual-core CPU with a clock frequency up to 240MHz. It integrates rich peripheral resources, including high-speed SDI0, SPI, and UART functions, and supports automatic downloading.
The ESP32 development board fully leverages the advantages of IoT development, making it a true IoT development tool. The display is controllable and can be used for remote control via an app, remote environmental data acquisition, remote data fusion, remote parameter setting, and other batch development applications.
