USB to TTL with ESP32 automatic download circuit

Overview

# USB to TTL module* The `TCPEC` version has been verified, and the `USBA` version has not been verified, but there will be no problems normally. * Bring a download circuit of `ESP32`. If it is not used, you don’t need to solder it. `EN` corresponds to `EN` of ESP32 or called `RST`, `IO0` corresponds to `IO0` of `ESP32`, which corresponds to `ESP32 -C3`'s `IO9`, please refer to the manual for other details. * Compatible with `CP2104` and `CH9012F`. If `CH9012F` is attached, the capacitor `C3` does not need to be soldered. * `BOM` is downloaded in the attachment. ![cgi-bin_mmwebwx-bin_webwxgetmsgimg_&MsgID=3954796415989906294&skey=@crypt_413d4b02_67102e2f382a083b02eeb70662367c18&mmweb_appid=wx_webfilehelper.jpg]
