They work just like the Dev boards, except, that they are not breadboard compatible, but you can jumper the pins to a breadboard using wires.
No soldering is needed and each has a power button (button with white top), to turn power on/off while USB is plugged in.
I currently own the WROVER version, and it's very nice. Very useful for jobs, that require programming before soldering the modules.
