  • Cost of producing one functional payload package: $362 

     

    Expected Cost of Mass Production

    The cost of producing one payload was $362. However, it’s worth noting that many of the parts we ordered are cheaper when ordered in bulk. For instance, 100 resistors cost about one penny, while ten resistors cost about fifteen cents, according to digikey’s website. Additionally, we ordered three SAM4S microcontrollers for $5 per microcontroller. If you order 100 microcontrollers, you are charged $3.50 per microcontroller. Every part we ordered on digikey has it’s price drastically reduced if you order by quantity of 100. With this method in mind, it is reasonable to conclude that the price of producing 100 functional payload packages will reduce the cost of each payload package by half.

    In other words, we believe the cost of producing functional payload packages for mass production will be about $180 per functional payload package, or $18000 to create 100 functional payload packages.
