There are several other shops selling this item.

I think the original shop is the GUITION official store at https://www.aliexpress.com/store/1102410813.

Brand and Type number

Guition 4848S040

Supplier information

  • To download the program via the USB-TYPE-C connector on MS-Windows, you probably need to install the driver for CH340, which is included in the driver package - no need to install a driver if you do not use MS-Windows.
  • Regarding computer power supply, it is not recommended to use a laptop USB port. Instead, use the USB 3.0 port of a desktop computer because the screen is in WiFi mode and the instantaneous current is relatively high. If the module still cannot be powered, you can try using a mobile phone charger to power it.

  • The LCD module adopts the Esp32-S3-Wroom-1 module as the main control, the main control is a dual-core MCU, which has integrated Wi-Fi and bluetooth functions. The main control frequency can reach 240MHz, has 512kiB SRAM, 384kiB ROM, 8MiB PSRAM. The flash size is 16MiB. The display resolution is 480*480. The display is of type IPS, and is fitted with capacitive touch. The module includes an LCD display screen, backlight control circuit and touch screen control circuit. There is a TF card interface and I/O Interface, the module supports Arduino IDE, ESP IDE, MicroPython, Mixly and other development environments.

  • Product Size: 86.00 X 86.00 X 14.00 MM / 3.39 X 3.39 X 0.55 Inch.
  • Type(Optional): 1 or 3 Way Relay.
  • ESP32-S3-N16R8 which is Espressif notation for 16MB QIO Flash and 8MB OPI PSRAM.
