The write up says it is RAMPS v1.4 compatible. So I would try one of the RAMPS type declarations. If you have one extruder, a fan, and a heated bed, I would use:
MKS Gen boards are RAMPS v1.4 compatible. So that probably will work too. Just pick one.... and see if everything moves correctly and the heaters work right.
If something doesn't work right, you can go after that one thing and change pin definitions.
