28-pin 0.3" to 0.6" socket adapter
This is a simple side project borne out of the necessity of having 0.3" SRAM chips and a 0.6" socket. Such adapters do exist, but it was actually cheaper to get three boards manufactured by OSH Park and buy a set of 0.3" 28-pin sockets. It even has a spot for an integrated decoupling capacitor.
