The NodeMCU ESP8266 V3 is 30mm wide, which takes up the whole breadboard width when plugged in, and that is where this expansion board comes in handy. If you are looking to prototype with the NodeMCU ESP8266 V3 board, then you will most definitely need this expansion board to access the pins with jumper wires.
The expansion board breaks out all the standard pins on the development board, as well as provide 3V, 5V and VIN pins for your power requirements. There is a voltage regulator on board so you can connect external 6V to 24V to power up the expansion board.
