This is an expansion board based on MEGA2560 R3, and the code(sketch) we provide is only used to test the experimental hardware.
If you need more functionality, write your own code. We do not provide additional code(sketch) and technical support
For more information details, please contact me.
How to use: See video

(You can search for videos on Google)
Note: Eletechsup
DNMEB50 is just an expansion board, it can
not work independently, must be under the control of the MEGA2560 R3 board to work,If you do not have a MEGA2560 R3 board, purchase it separately or purchase a kit with MEGA2560 R3
