My RF design rules paid off! The 5 ns edge from the STM32H7 GPIO is one of the purest edges I've ever seen, even though I'm using a two-layer board (which features 120 Ω all-microstrip routing on a gapless plane, source termination, and one ground per signal test point). It's even cleaner than my clip-connected function generator. #electronics #NES #NESdev
