Hi,

This is my first time working away from Arduino.

I am creating a simple CAN bus analyser using a STM32F105RBT6

I have used parts of circuits from various evaluation boards.

But I am mainly concerned about the Power circuit. I want to be able to power from VIN or USB. Both are to be able to be powered at the same time.

I have also seen similar circuits using a 8mhz or 25mhz so I am not sure which to use.

The Image dialog on here doesn't seem to work on Safari or Chrome on Mac so please check out this post:

Hi gould.terry,

If you still need some help to implement your STM32F105 based board, I recommend you to refer to AN2586: Getting started with STM32F10xxx hardware development.

You find there more tips on how to design your hardware taking into accounts device characteristics.
