1,Overview

ESP32-8048S070C is a development board for visual touch screen, the board is equipped with GUI platform firmware developed independently, support graphic drag and drop programming to help users complete the development of customized control platform. The main controller of ESP32-8048S070C development board adopts ESP32-S3-WROOM-1 module, this module is a general-purpose Wi Fi + Bt + ble MCU module, 16MB SPI flash and 8MB PSRAM are configured in.ESP32-8048S070C development board can also develop and debug functions such as buttons, voice and camera through the expansion interfaces on both sides, greatly shorten the development cycle of users.

2,The following hardware resources

1) ESP32-S3-WROOM-1 Module

ESP32-S3-WROOM-1 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-S3-WROOM-1 are:8Mbyte PSRAM + 16Mbyte Flash.

2) TP Interface

Capacitive touchpad interface, I2C interface, 0.5mm spacing, 6pin, flip down type.

3) LCM Display interface7.0-inch LCM display interface, SPI interface, 1.25mm spacing, 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-7.0Inch; Pixel density-165PPI; Resolution:800*RGB*480; Screen model:

ESP32-8048S070C

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-S3, it ensures the stability of the esp32-S3.

5) External power interface

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

6) RST Key

Touch the self-reset button to connect to the EN pin of ESP32-S3. This button can be used to reset ESP32-S3.

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.

3,Power On Instructions

1) Power supply

This development board supports USB Type-C 5V power supply and reserved external power input interface (as shown by reference number 5 in Figure 3). It is recommended

that the input voltage 5V support current is not less than 1A when other expansion boards are not inserted, and the input voltage 5V support current is not less than 2A when other expansion boards are inserted (refer to the actual power consumption of the expansion board for details). Note: When the external power supply is provided through the reserved power interface, the power supply voltage input range is 5V, and the load current is recommended to be I> 2A.

2) Precautions

Please make sure that the FPC cables of the TP and LCM screens have been inserted into the corresponding FPC sockets before powering on the development board, otherwise

4,Board Electrical Parameters

Test environment:

1,Temperature: Room temperature 25 ℃

2,Power supply: 5.0V Voltage ripple V

Test parameters:

1,Normal working current: 500mA(Average current)

5, Firmware Burning

1) Step One:

Connect the ESP32-8048S070C board to the computer via the USB-TypeC data cable. Since this development board has automatic data flow control processing, the firmware can be automatically downloaded through ESP32 Flash_Download_Tools.

2) Step Two:

As shown in Figure 7-1 below: Select the firmware path to be burned at 1. The address is usually 0X00. After setting, remember to tick the front; Select the system clock to be 40MHz at 2 locations; Choose the size of Flash as 128Mbit in 3 places; Select SPI MODE as DIO mode at 4 places; Select the port number of the current board recognized by the computer at 5; Select the serial port baud rate at 6 places (the larger the value, the faster the firmware download rate, and the maximum support is 1152000bps); After completing the previous configuration, click at 7 to start burning the firmware.

3) Step Three:

After completing the above two steps, press the reset button on the back of the
development board to start running the firmware just burned.
