ESP32 + LAN8720 advice

Postby artyomka71 » Wed Jun 09, 2021 5:13 am

Hi!

Help is required to connect the LAN8720AI-CP-TR to the ESP32 .
I built a scheme where LAN8720 is required, I took the Olimex ESP32-POE solution as a basis and read the information in the LAN8720 Datasheet . The final scheme is shown in the attachment. I ordered the board on jlcpcb, then I flashed it with ESPhome, but the Ethernet does not work :? . WI-FI works very well. I think that somewhere I have an error in the scheme, but I do not see it. Help me find the mistake in the scheme.

The ESPHome settings are as follows:

Code: Select all

esphome:
  name: arthome_module_lan
  platform: ESP32
  board: esp-wrover-kit

ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk_mode: GPIO17_OUT
  phy_addr: 0
  power_pin: GPIO12

  # Optional manual IP
  manual_ip:
    static_ip: 192.168.1.52
    gateway: 192.168.1.1
    subnet: 255.255.255.0
