GPIO Angle Adapter - 90 Degree 40 Pin
These 90 degree GPIO adapters bring the GPIO pins out to the side instead of straight up. This works well for the cluster stack as it puts the GPIO pins in a more usable position. These are also useful for single SBCs as well.
These are compatible with the 40 pin GPIO blocks on the Raspberry PI, Odroid C2, and Pine64 boards.
