Project description

This link leads to a product page on eBay for a development board named "YB-ESP32-S3-ETH". The product includes features such as ESP32-S3, Ethernet, WiFi, 8MB Flash/PSRAM, and 2xUSB. The product is brand new, unopened, and undamaged in its original packaging. Notable features of the product include Ethernet and USB, and the type of program storage is Flash. The working memory size is 8MB Flash and 8MB PSRAM. This product belongs to the Arduino Development Board series.

  • ESP32-S3-WROOM-1U-N8R8 module with Espressif's modern ESP32-S3 MCU, 8MB Flash, 8MB PSRAM and WLAN/BT IPEX antenna connector
  • RJ45 10M/100M Ethernet connector driven by onboard PHY controller chip Wiznet W5500
  • The W5500 pins required to control the chip are hardwired to the ESP32-S3 GPIOs as follows:
    • MOSI - GPIO11, MISO - GPIO13, SCK - GPIO12 (SPI bus data communication)
    • SCS - GPIO14 (chip select, required for SPI bus control)
    • RST - GPIO21 (chip reset, needed only for chip reset without resetting the whole board)
    • INT - GPIO18 (only if solder bridge on bottom is closed, seldomly needed)
  • Two control LEDs. One LED labeled 'P' is connected to the 3.3V rail to indicate board power and the other LED labeled 'IO47' is connected to GPIO47 which can be used as status LED, for debugging purposes etc.
