I’m researching about dc-dc converters and this little boy is perfect: https://www.pololu.com/product/2574
I’m having currently a buck converter (step-down) very close to the wifi-bluetooth module of my raspberry pi in my project.
I want to upgrade it to an step-down-step-up like the one linked. How much noise is going to add to my bluetooth communication? how much is going to kill my signal range? Is there any data about that?
Is there a way of avoiding the radio noise, like shielding it?
Any tips and / or recommendations will be greatly appreciated.
