I've received a number of emails about a few jumpers that have been added to the NovaDrone PCB. These were added to the board to unlock a cool feature we found after ordering the last batch of PCBs. I have written a more detailed note about it on the <a href="http://casperelectronics.com/finished-pieces/nova-drone/novadrone-sales-page/">sales page</a>. Its tough to decide whether modifications should be made to boards, especially when you have to make that mod to 100 boards. but the new feature we found was just to fun to not include.
