When writing/porting applications to the Curiosity demo board I found myself looking over and over at the schematic (contained in the User Guide) for the connections between the 20-pin socket and the click board (mikroBUS) connector. Crossing this information with the peripherals and capabilities on chip was not easy. This got old very quickly, so after a couple of days, I drew the tables below:
These made a big difference to me. Hope they will be useful to you (and all other Rocket Scientists) as well.
