Replacement Circuit Board for a HappiJac Electric Truck Camper Jack

Question

Question:

The left front fuse port melted due to a shorted motor. I replaced the motor only to find that the circuit board got toasted. On this board I do not see a model number. In your videos they refer to your original circuit boardinch and give the replacement board information. HJ info, 733513. I have looked through the Q/A and kinda see the answer. I attached a few photos for clarity. This truck camper is a 2017 Northern lite 8-11, no doubt the year of the board and controller. I need a controller, but do I need a new remote too? I hope not, everything is so high in costs.
