Hardware Resource The hardware resources of the development board are as follows: Figure 2 shows the physical front view of the development board. It consists of a 3.5-inch LCD screen with a resolution of 320x480 and a capacitive touch pad, and it Supports two touch. Figure 3 is the physical figure on the back of the development board, which contains the following hardware resources: 1、ESP32-WROVER-B Module Esp32-wrever-b is a Wi Fi + Bt + ble MCU module for all kinds of applications.
6、RST Key Touch the self-reset button to connect to the EN pin of ESP32. This button can be used to reset ESP32. 7、Type-C Interface Universal USB-C interface (Type-C interface), this interface is used to power the development board, UART communication and firmware download. The hardware of the download circuit implements data flow control, so the firmware download supports oneclick automatic download.
