This is the header we use for the -FM and -FM1 connector options on our Adapt-series MCU, application, and accessories products. It is a quality stackable header at about half the price of the Samtec part we used to use. Unlike the stackable headers commonly used with Arduino, these pins are square (not rectangular).
