📄 Description

This is based on Olimex ESP32-PoE-ISO
https://www.olimex.com/Products/IoT/ESP32/ESP32-POE-ISO/open-source-hardware

It has a SD Card slot that is used to store all filesystem data on SD.
Use the prepare_sdcard.sh script to copy all needed data to an empty
SD card that is formatted with FAT filesystem. The AP firmware will format
the SD if an unformatted or from formatted card is used. This can be used
to intially prepare an empty SD card for usage.

For tag communication a ESP32-C6-WROOM-1(U) is used with the following
connection scheme:

ESP32-PoE-ISO ESP32-C6-WROOM-1
GPIO5 EN
GPIO13 GPIO9
GPIO36 GPIO3
GPIO4 GPIO2
GPIO33 GPIO24
GPIO32 GPIO25
GPIO8 pullup 5.1k

The AP has support for PoE/Ethernet, for that the new added Ethernet
support allows to make the network/internet connection
via LAN cable instead of WiFi. LAN is preferred, if a LAN cable is
connected and a valid IP configuration via DHCP can be obtained, WiFi
is switched off. If the LAN cable is disconnected, a fall back to
WiFi is done.

Use those defines in platform.ini for PHY settings:

  • ETHERNET_PHY_POWER: IO pin where the PHY can be switched of/on, can be -1 if not used.
  • ETHERNET_CLK_MODE: PHY clock mode, see eth_clock_mode_t in ETH.h
  • ETHERNET_PHY_MDC: PHY MDC pin
  • ETHERNET_PHY_MDIO: PHY MDIO pin
  • ETHERNET_PHY_TYPE: PHY type, see eth_phy_type_t in ETH.h

Limitations:

  • only DHCP is supported, no static IP configuration for LAN so far.
  • If GPIO0 is used for one of the ETHERNET_CLK_MODE modes, then GPIO0
    cannot be used to clear the WiFi configuration.
