Sorry last question. I really have problem understanding this "4) Moving almost exclusively to the NodeMCU I've had to adjust my circuits to adjust to 3.3V vs the Arduino 5V standard. Google is your friend. A simple voltage divider works in most cases. Power the 5V device from the USB In pins of the breakout board, but use a voltage divider on the pins back to the NodeMCU so they are 3.3V."
I kind of get that the LCD board needs 5v. The NodeMCU only gives me 3.3V, how do I get 5v from the board?
