Supports Multe PeripheralsSupports The Expansion Of Multe Peripherals Via Sensor, CAN, RS485, And I2C Interfaces

- UART interface: Using CH343P chip for USB to UART to connect to ESP32-S3's UART_TXD(GPIO43) and UART_RXD(GPIO44), enabling ing and log printing.- USB interface: GPIO19(DP) and GPIO20(DN) are the USB pins of ESP32-S3 by default, and the interface can be used for connecting cameras with protocols such as UVC.- Sensor interface: this interface is for connecting GPIO6 as ADC, and can be connected to .- CAN interface: The CAN interface pins and USB interface pins share a multexed function, utilizing the FSUSB42UMX chip for switching. By default, the USB interface is used (when the USB_SEL pin of FSUSB42UMX is set to HIGH).- I2C interface: ESP32-S3 offers multe hardware I2C interfaces. Currently, GPIO8 (SDA) and GPIO9 (SCL) pins are used as the I2C bus to connect to the IO expansion chip, touch interfaces, and other I2C peripherals.- RS485 interface: The development board is equipped with an onboard RS485 interface circuit, allowing direct communication with RS485 devices. The RS485 circuit automatically switches between nsmit and receive modes.- PH2.0 battery header: The development board employs the efficient charging and discharging management chip C501, capable of boosting a single lithium battery to 5V. Currently, the charging current is set at 580mA. Users can modify the charging current by replacing the R45 . For further details, please refer to the schematic diagram.

Hardware Connection- ESP32-S3-Touch-LCD-4.3 comes with an onboard automatic download circuit. The Type C port, marked UART, is used for program downloads and loing. Once the program is downloaded, run it by preing the RESET on.- Please keep other metals or plastic material away from the area during use.- The development board uses a PH2.0 connector to extend ADC, CAN, I2C, and RS485 peripheral pins. Utilize a PH2.0 to 2.54mm DuPont male connector to link sensor components.- As the 4.3-inch screen occupies most GPIO pins, you can use a CH422G chip to expand IO for functions like reset and backlight control.- The CAN and RS485 peripheral interfaces connect to a 120 using jumper caps by default. Optionally, connect NC to cancel the termination .- The SD card employs communication. Note that the SD_CS pin needs to be driven by the EXIO4 of the CH422G.Package includes:
