Far Cry New Dawn is, unlike its predecessors, a bit of an RPG-lite experience, and with that territory comes the need to farm various materials to craft better weaponry.
Far Cry New Dawn Circuit Boards are one of the most important rare resources, and you need them for virtually any high-end weapon worth a damn. These firearms will be key for your completion of late-game missions, so you'd do well to stock up on Circuit Boards in advance.
Circuit Boards are a rare resource primarily awarded for the completion of various Expeditions, though you can also get a few by trading certain Monstrous animal skins. To be more exact, completing a 0-star Expedition will net you 15 Circuit Boards, while each animal skin traded nets you 10 Circuit Boards.
The key is to keep completing more high-end Expeditions as you move along (farm them out, if you will), because as the difficulty rises, so does the reward. The maxed-out 3-star Expedition, for example, will award you 25 Circuit Boards on completion, which is a marked improvement over the standard 10.
To craft every single weapon in the game, you will need to have collected about 200 Circuit Boards total, which isn't a ridiculous amount, but you might have to put some work in it after all.
