I once called this the "Horse Pill" because it is so big. It is big both in capability (480 Mhz, 2M flash, 1M ram) and in physical size (nearly 3x5 inches). For comparison, the "blue pill" is pretty much 1x2 inches.
I bought my STM32H743 Nucleo-144 from Digikey in December of 2020 for $30 and of course got it in short order via the US mail.
A note: 6 years later (September of 2026) this board is discontinue and no longer available. You would now buy the STM32H753 Nucleo for $40.81. It is the same, and pin compatible, but includes crypto hardware as well as secure boot features. For a few dollars more ($43.53) you can get the STM32H755 Nucleo which is a dual core variant.
