Hi everyone,

 

I would like to ask you for help.

I am designing custom board derived from Netduino. The basic aim is to have a lots of GPIO on just one board. I have done my first scheme. But I have never done this before. So I really do not know, if my scheme is correct.

Could you please check my scheme for any design errors, bad practice, etc. , and also set correct packages for all components?

 

Attached is my version of the scheme, made in Eagle 7.3.0 light, renamed to .txt so I can upload it here.

 

My last question, when I solder fresh new MCU on the board, does it already contain minimum code needed to communicate with STDfuse demonstration tool over USB? Or I have to flash something over MCU's programming interfaces?

 

Thanks in advance.

I guess you should check the datasheet for the given microcontroller (you don't say which netduino you are cloning), and reading a bit about the bootloader and stuff..

Hi,

 

Thanks for reply. I can check datasheet, but I would still be glad, if someone, who has already done this before, could check my scheme. You know, I can misunderstand the datasheet. Also, I don't think, I will find correct packages for resistors,capacitors, etc. in the datasheet. 

 

STM32F405 was originally used in Netduino Plus 2. I have used Frode's board (found here: http://forums.netdui...ler-netduino-2/) as a reference.
