I am still using the STM32F405 with the Cerbuino for small one off projects but I have a question on the IO ports shown in the schematic for the Cerbuino Bee. I need clarification on which pins the functions appear as there is 2 for some functions.
PA6 shows SPI1_MISO and so does PB4. Which is the correct one? I am guessing PB4 as that is routed to X1
PB6 shows I2C-SCL, PB7 shows I2C-SDA and so does PB10 and PB11. Which is the correct one? I assume PB6 as this is routed to X2.
Which pins does the CAN bus appear one?
Which pins for SPI2?
