We sought permission from evolv to use key parts of their open source reference 510 connector to base our new 510 design on. While they look similar from the outside the changes are significant enough for none of the parts to be compatible between connectors so please don't buy these to transplant parts. At best just the nut and solder lug will be compatible but there's no guarantee.
