I was wondering if anybody can provide me an answer to this issue, I have three devices fixed to the Arduino Due Shield which are connected to the 5V pin but I have realised that the total power consumption would be 3.2A, I found out that the TI regulator is recommended for 1A suppy (but it has a switching current limit of 1.2A to 2.5A).
I was wondering if my assumption would work, by connecting a DC-DC linear regulator with current limit of 4A converted from my 12V supply down to 5V and is then connected to the 5V pin on the Arduino Due and then running the 12V supply through the Arduino Due DC Jack? Would I have issues with this setup or should I no bother connecting the 12V suppply to the DC jack?
I have attached an image to hopefully make things clear.
I hope to hear from you guys, and in advance thank you.
