Everything ARM and LPC

Has anyone tried replacing the STM32F103 chip on the STM32F103 header board with a STM32F4 chip?

According to ST, the M4 cortex is pin to pin compatible, and having 1 M of flash, running at 168 MHz and having a floating point unit on board sounds kinda cool to me.

I doubt if anyone else has tried it, why not have a go?

Which STM32F103 header board have you got? I might try it.

One thing different about the STM32F4XX (and STM32F2XX) compared to the STM32F1XX is that they both need a 2.2uF low ESR cap on the VCAP_1 and VCAP_2 pins.
