Preheat the oven to 350 degrees F and line a baking sheet with parchment paper.
In a mixing bowl, stir the pecan halves with the maple syrup until evenly coated. Add the brown sugar and cinnamon, then toss again to distribute the coating.
Spread the pecans in a single layer on the prepared baking sheet. Bake for 12 to 15 minutes, stirring once halfway through, until the coating looks set and the pecans smell toasted. Remove from the oven and let them cool completely on the sheet.
Arrange the cooled candied pecans in one section of a serving board. Place the maple candy pieces, caramel candies, and dark chocolate squares in separate sections around the pecans to create an easy grazing layout.
