ESP32 Forum

i wish to use ESP32 as an USB mass storage, may i know any idea or suggestion how to archive this ?

As the ESP32 does not support USB natively out-of-the-box, I'd suggest finding a chip that can act as an USB host that's e.g. connected over SPI.

Could you or someone suggest such chip/IC ?
I know older usb-flash devices use serial sata-to-usb IC and might be similar to SD card interface in ESP

There are boards on the market that use MAX3421 as USB HOST adaptor.

Thank you !

With ESP-Sx (S2 and S3) is possible since they have native USB support. No extra HW required
