ESP32 Forum

Hi,
I want to connect the driver LAN8742 to ESP32 for the ethernet port.
Have I connected the right pins?


RMII_RXD0 to IO25
RMII_RXD1 to IO26
RMII_CRS_DV to IO27
RMII_MDC to IO23
RMII_TXD1 to IO22
RMII_TX_EN to IO21
RMII_TXD0 to IO19
RMII_MDIO to IO18
RMII_REF_CLK to IO0


thanks in advance.

Those are the pins I connected my LAN8720 to and it works ok. Take care with GPIO0 to prevent it entering flash mode accidentally from the clock input though.

Yes those are the correct pins. Care must be taken on GPIO0 to on startup to prevent it booting into flash mode thugh.
