FAQ
Q: Can the wires be replaced if I want to move it to a new project? What are the wire connections called?
A: The white connector space is 1.27mm, if you want to use it for other projects, there is no need to change whole cable, you just need to solder female dupont cable or male dupont cable, then add heat shrink on the solder position, please check this picture http://s5.ecpperp.com/flyfun/data/upload/product_img/190411/FZ2904A.png
