it seems like PC9 is the only pin w/ I2C3_SDA on the lqfp64 stm32f4 - #149

Can we confirm the Revo Nano uses a STM32F411. PC9 is the only I2C3 SDA on that chip - even in the 64 qfp - though the Revo uses the BGA package ??? |

thx for the review @blckmn! maybe we want something more like this? |

I think this will be good. Anyone with a Nano that can test? @rs2k |

I'll test this out soon. I've got my revonano still hooked up from testing BLHeli VCP. |

it looks like, from the datasheet, that
PB4's AFs areNJTRST/ SPI3_MISO / TIM3_CH1 / SPI1_MISO / I2S3ext_SD/ EVENTOUT(I2S3ext_SD!=I2C3_SDAright?) and the only pin w/I2C3_SDAisPC9the only target that uses
I2CDEV_3is theREVONANO. if anyone is using gps on this target, can they confirm it's broken or working?
