Yes and no. I used protoboard to put my permanent WLED setup together. The complexity of the ESP32 is contained on its own board, the I2S microphone came from Ali in breadboard friendly form, the IR Receiver and LED terminal block were leaded components, etc. Protoboards are a good option for making anything you've built up around an ESP or Arduino on a breadboard more permanent as long is it doesn't have to stand up to rough handling. This covers a lot of ground in the maker community.
