The following hardware resources

1) ESP32-WROVER-B Module
ESP32-WROVER-B is a Wi Fi + Bt + ble MCU module for all kinds of applications. It has powerful functions and wide applications. It can be used in low-power sensor networks and demanding applications, For example, voice coding, audio streaming and MP3 decoding. The parameters of this ESP32-WROVER-B are:8Mbyte PSRAM + 4Mbyte Flash.

2) TP Interface
Capacitive touchpad interface, I2C interface, 0.5mm spacing, 6pin, flip down type.

3) LCM Display interface3.5-inch LCM display interface, SPI interface, 0.5mm spacing, 24pin. This SPI interface is connected to the hardware HSPI interface of esp32, the operating clock frequency can
reach 80MHz. The screen parameters used are: Size-3.5Inch; Pixel density-165PPI; Resolution:320*RGB*480; Screen model: WT-352215-A2.

4) Power management
Two LDOS of 3.3V output, One supplies power to the board itself, The other supplies power to the external expansion board, The power supply is separated to prevent the expansion board from interfering with the power supply of esp32, it ensures the stability of the esp32.

5) External power interface
Reserved external power interface (positive and negative as shown in + - sign on the figure), input voltage range 5v-9v, maximum load current I > 2A.

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 one- click automatic download.

8-9) Expansion Board Interface
The interface of the external expansion board can be used for power supply, communication, control, etc. So as to achieve functional expansion to meet the various needs of users. The 8 and 9 interfaces are connected by Pin to Pin, so the circuit connection of the expansion board inserted into the 8 interface and the 9 interface is the same, but only to meet the user's experience of installing the expansion board in different directions. Simultaneously: When the IO of the two expansion boards does not conflict, two expansion boards can be inserted at the same time to achieve two expansion functions. Expansion board interface specifications: 2.0mm pitch, 2X20Pin, can be installed on both sides of the horizontal row. The interface definition is shown in Figure 3-Extended Edition Interface Definition Diagram.

10) Power Indicator
The power indicator (red light) lights up when you plug in the USB cable.

11) UART Communication Indicator
The TXD indicator and RXD indicator in the UART will flash when there is data flow.
