Is the STM32F4 break out board compatible with STM32F429i-DISC1
If you by break out board mean STM32F4DIS-BBSTM32F4DIS-BB STM32F4DIS-BB STMICROELECTRONICS, Expansion Board for STM32F4-DISCOVERY, Support for uC/OS-II_v2.86 OS, SPI, I2C, CAN In… ), then no. Expansion pin headers on STM32F429I-DISC1STM32F429I-DISC1are longer(2 times 2x32 pin than on STM32F4DISCOVERY(2 times 2*25 pin for which is STM32F4DIS-BBSTM32F4DIS-BB designed
