Clarification Needed: Is the MAX485 Module Interface to the MCU SPI or UART?

Hi everyone,

I’m currently working with a MAX485 module and connecting it to my MCU (specifically an ESP8266). My teacher mentioned that the interface on the MCU side is SPI, but I’m not entirely sure if that’s correct. From what I’ve researched, I believe it should be UART instead.

Could someone please clarify whether the MAX485 module communicates with the MCU via SPI or UART? I’d really appreciate any guidance or correction on this.

Thanks in advance!

MAX485

is a chip that able to provide communication over RS-485 protocol, and it is sort of serial bus.
both side are equal. SPI is serial too, but one side is controller(old master), every other - a periphery (old slave)
