Comments on Breakout board for STM32

I have made a schematic of breakout board for STM32F205RBT6.

I will make a square board with all pins from MCU coming out to outer 2.5mm headers.

1. Symbols in schemtaic with name ''Nx'', are bascially are small jumpers with 0805 size.

2. I have some odd debug connector here. I have made this kind of connection for other boards so that's not a problem.

Any comments/suggestions on ckt.

Hello.

1. check waveshare boards.

2. put VCC and especially OSC pin to headers will maybe bring EM noices.

.... so consider putting a jumper (Nx) that allows you to interrupt the oscillator pins going to the header.

You can also cheat by looking at schematics for ''discovery'' boards, and the nucleo. The nucleo is complicated because a single PCB supports many different CPUs.
