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

it looks like, from the datasheet, that PB4's AFs are NJTRST/ SPI3_MISO / TIM3_CH1 / SPI1_MISO / I2S3ext_SD/ EVENTOUT (I2S3ext_SD != I2C3_SDA right?) and the only pin w/ I2C3_SDA is PC9

the only target that uses I2CDEV_3 is the REVONANO. if anyone is using gps on this target, can they confirm it's broken or working?

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.
