To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I originally purchased the NoIR version and it wouldn’t even connect to my pi. I purchased the other version and it did connect but would not show any picture. I went into Terminal and did everything I possible could only to debug and find that the module was damaged. I will be returning both and purchasing from another seller.
