Hey people, since I'd like to be independent from the availability of the STM32F4-discovery board I started designing my own board, which has an STM32F407VGT6 on board. Its an LFQP 100 package, so not easy to solder. I have a reflow oven and the first PCB I made seems to work fine. The PCB has very few components. This was just a quick test board to see if the basic circuit of the STM32F4 is working. It's basically just the STM itself and it's components like caps and crystal. Also the
