Dev board return policy

Development boards are specialty items that generally cannot be resold on return, especially if the firmware has been flashed. Defective boards can be replaced or returned for refund within 30 days of purchase. Non-defective boards can be returned in the same time frame if in like-new condition with a 20 percent restocking fee applied. If the board has had altered firmware or became bricked due to a non-standard firmware flash, the board may not be eligible for return.
