MITE-ESC (SySch415)ECADConfidence: Medium

On a small ESC board, MISO and MOSI went to STM32 pins with no SPI1 function, so hardware SPI cannot work as routed. The firmware fallback exists, but the author would rather not have to redefine the pin map. A classic schematic, layout and firmware handoff miss.
