There's a million of these, but this one fits the 38pin ESP32 WROOM devkits from az delivery etc. Should work for either the usb-c or mini-usb connectors on the one side with a small hole on the other side for the power. & data lines to upstream LEDs.

I used these as part of a project converting chinese fairy lights at christmas time (https://github.com/ciaranj/wled-fun/tree/main/hello-fairy-net)
